meillo@0 4 masqmail.conf \- masqmail configuration file
meillo@34 5
meillo@34 6
meillo@0 7 .SH DESCRIPTION
meillo@0 8
meillo@34 9 This man page describes the syntax of the main configuration file of masqmail.
meillo@34 10 Its usual location is \fI/etc/masqmail/masqmail.conf\fR
meillo@0 11
meillo@0 12 The configuration consists of lines of the form
meillo@0 13
meillo@34 14 \fBval\fR = \fIexpression\fR
meillo@0 15
meillo@34 16 Where \fBval\fR is a variable name and \fIexpression\fR a string,
meillo@34 17 which can be quoted with double quotes `"'.
meillo@34 18 If the expression is on multiple lines or contains characters other than letters,
meillo@174 19 digits or the characters `.', `-', `_', `/', ';', '@', ':', it must be quoted.
meillo@34 20 You can use quotes inside quotes by escaping them with a backslash.
meillo@0 21
meillo@174 22 Each \fBval\fP has a type, which can be boolean, numeric, string or list.
meillo@34 23 A boolean variable can be set with one of the values `on', `yes', and `true' or `off', `no' and `false'.
meillo@34 24 List items are separated with semicolons `;'.
meillo@174 25 For some values, patterns (like `*',`?') can be used.
meillo@174 26 The spaces in front of and after the equal sign `=' are optional.
meillo@0 27
meillo@34 28 Most lists (exceptions: \fBlocal_hosts\fR, \fBlocal_nets\fR, \fBlisten_addresses\fR,
meillo@139 29 \fBonline_routes\fR, and \fBonline_gets\fR) accept files.
meillo@34 30 These will be recognized by a leading slash `/'.
meillo@34 31 The contents of these files will be included at the position of the file name,
meillo@34 32 there can be items or other files before and after the file entry.
meillo@174 33 The format of the files is different though, within these files each entry is on another line
meillo@174 34 and the entries are not separated by semicolons.
meillo@34 35 This makes it easy to include large lists which are common in different configuration files,
meillo@34 36 so they do not have to appear in every configuration file.
meillo@0 37
meillo@34 38 Blank lines and lines starting with a hash `#' are ignored.
meillo@34 39

meillo@0 41 .SH OPTIONS
meillo@34 42
meillo@0 43 .TP
meillo@34 44 \fBrun_as_user = \fIboolean\fR
meillo@0 45
meillo@34 46 If this is set, masqmail runs with the user id of the user who invoked it and never changes it.
meillo@34 47 This is for debugging purposes only.
meillo@34 48 If the user is not root, masqmail will not be able to listen on a port < 1024
meillo@34 49 and will not be able to deliver local mail to others than the user.
meillo@0 50
meillo@0 51 .TP
meillo@34 52 \fBuse_syslog = \fIboolean\fR
meillo@0 53
meillo@34 54 If this is set, masqmail uses syslogd for logging.
meillo@34 55 It uses facility MAIL.
meillo@34 56 You still have to set \fBlog_dir\fR for debug files.
meillo@0 57
meillo@0 58 .TP
meillo@34 59 \fBdebug_level = \fIn\fR
meillo@0 60
meillo@34 61 Set the debug level.
meillo@34 62 Valid values are 0 to 6, increasing it further makes no difference.
meillo@34 63 Be careful if you set this as high as 5 or higher, the logs may very soon fill your hard drive.
meillo@0 64
meillo@0 65 .TP
meillo@44 66 \fBlog_dir = \fIfile\fR
meillo@44 67
meillo@174 68 The directory where logs are stored, if syslog is not used.
meillo@174 69 Debug files are always stored in this directory if debugging is enabled.
meillo@44 70 \fIfile\fR must be an absolute path.
meillo@44 71
meillo@151 72 Default: \fI/var/log/masqmail\fR
meillo@151 73
meillo@44 74 .TP
meillo@34 75 \fBmail_dir = \fIfile\fR
meillo@0 76
meillo@34 77 The directory where local mail is stored, usually \fI/var/spool/mail\fR or \fI/var/mail\fR.
meillo@44 78 \fIfile\fR must be an absolute path.
meillo@0 79
meillo@152 80 Default: \fI/var/mail\fR
meillo@152 81
meillo@0 82 .TP
meillo@34 83 \fBspool_dir = \fIfile\fR
meillo@0 84
meillo@34 85 The directory where masqmail stores its spool files (and later also other stuff).
meillo@34 86 It must have a subdirectory \fIinput\fR.
meillo@34 87 Masqmail needs read and write permissions for this directory.
meillo@44 88 \fIfile\fR must be an absolute path.
meillo@0 89
meillo@151 90 Default: \fI/var/spool/masqmail\fR
meillo@151 91
meillo@0 92 .TP
meillo@133 93 \fBlock_dir = \fIfile\fR
meillo@133 94
meillo@133 95 The directory where masqmail stores its lock files.
meillo@133 96 Masqmail needs read and write permissions for this directory.
meillo@133 97 By default it is a directory ``lock'' inside of \fIspool_dir\fP.
meillo@133 98 \fIfile\fR must be an absolute path.
meillo@133 99
meillo@133 100 .TP
meillo@34 101 \fBhost_name = \fIstring\fR
meillo@0 102
meillo@34 103 This is used in different places: Masqmail identifies itself in the greeting banner
meillo@34 104 on incoming connections and in the HELO/EHLO command for outgoing connections with this name,
meillo@34 105 it is used in the Received: header and to qualify the sender of a locally originating message.
meillo@0 106
meillo@34 107 If the string begins with a slash `/', it it assumed that it is a filename,
meillo@34 108 and the first line of this file will be used.
meillo@34 109 Usually this will be `/etc/mailname' to make masqmail conform to Debian policies.
meillo@0 110
meillo@34 111 It is not used to find whether an address is local. Use \fBlocal_hosts\fR for that.
meillo@0 112
meillo@156 113 Default: none; \fBhost_name\fP MUST be set in the config file
meillo@156 114
meillo@0 115 .TP
meillo@34 116 \fBlocal_hosts = \fIlist\fR
meillo@0 117
meillo@34 118 A semicolon `;' separated list of hostnames which are considered local.
meillo@153 119 Normally you should set it to "localhost;foo;foo.bar.com" if your host has the
meillo@34 120 fully qualified domain name `foo.bar.com'.
meillo@0 121
meillo@157 122 Default: localhost ; <value of \fBhost_name\fR cut at the first dot> ; <value of \fBhost_name\fR>
meillo@157 123
meillo@157 124 Example: \fIlocalhost;foo;foo.example.org\fR
meillo@157 125 (if you have set \fBhost_name\fR to \fIfoo.example.org\fR)
meillo@153 126
meillo@0 127 .TP
meillo@34 128 \fBlocal_nets = \fIlist\fR
meillo@0 129
meillo@34 130 A semicolon `;' separated list of hostnames which are on the `local' net.
meillo@34 131 Delivery to these hosts is attempted immediately.
meillo@34 132 You can use patterns with `*', e.g. "*.bar.com".
meillo@0 133
meillo@0 134 .TP
meillo@34 135 \fBlocal_addresses = \fIlist\fR
meillo@0 136
meillo@34 137 A semicolon `;' separated list of fully qualified email-addresses which are
meillo@34 138 considered local although their domain name part is not in the list of \fBlocal_hosts\fR.
meillo@0 139
meillo@34 140 For example: There are two people working at your LAN: person1@yourdomain and person2@yourdomain.
meillo@34 141 But there are other persons @yourdomain which are NOT local.
meillo@34 142 So you can not put yourdomain to the list of local_hosts.
meillo@34 143 If person1 now wants to write to person2@yourdomain and this mail should not leave the LAN then you can put
meillo@0 144
meillo@0 145 local_addresses = "person1@yourdomain;person2@yourdomain"
meillo@0 146
meillo@0 147 to your masqmail.conf.
meillo@34 148
meillo@0 149 .TP
meillo@34 150 \fBnot_local_addresses = \fIlist\fR
meillo@0 151
meillo@34 152 A semicolon `;' separated list of fully qualified email-addresses which are
meillo@34 153 considered not local although their domain name part is in the list of \fBlocal_hosts\fR.
meillo@0 154
meillo@34 155 This is the opposite of the previous case.
meillo@34 156 The majority of addresses of a specific domain are local.
meillo@34 157 But some users are not.
meillo@34 158 With this option you can easily exclude these users.
meillo@0 159
meillo@0 160 Example:
meillo@0 161
meillo@0 162 local_hosts = "localhost;myhost;mydomain.net"
meillo@0 163
meillo@0 164 not_local_addresses = "eric@mydomain.net"
meillo@34 165
meillo@0 166 .TP
meillo@34 167 \fBlisten_addresses = \fIlist\fR
meillo@0 168
meillo@34 169 A semicolon `;' separated list of interfaces on which connections will be accepted.
meillo@34 170 An interface ist defined by a hostname, optionally followed by a colon `:' and a number for the port.
meillo@34 171 If this is left out, port 25 will be used.
meillo@0 172
meillo@34 173 You can set this to "localhost:25;foo:25" if your hostname is `foo'.
meillo@0 174
meillo@34 175 Note that the names are resolved to IP addreses.
meillo@34 176 If your host has different names which resolve to the same IP,
meillo@34 177 use only one of them, otherwise you will get an error message.
meillo@0 178
meillo@161 179 Default: \fIlocalhost:25\fR (i.e. only local processes can connect)
meillo@161 180
meillo@0 181 .TP
meillo@34 182 \fBdo_save_envelope_to = \fIboolean\fR
meillo@0 183
meillo@34 184 If this is set to true, a possibly existing Envelope-to: header in an incoming mail
meillo@34 185 which is received via either pop3 or smtp will be saved as an X-Orig-Envelope-to: header.
meillo@0 186
meillo@34 187 This is useful if you retrieve mail from a pop3 server with either masqmail or fetchmail,
meillo@34 188 and the server supports Envelope-to: headers,
meillo@34 189 and you want to make use of those with a mail filtering tool, e.g. procmail.
meillo@34 190 It cannot be preserved because masqmail sets such a header by itself.
meillo@0 191
meillo@0 192 Default is false.
meillo@34 193
meillo@0 194 .TP
meillo@34 195 \fBdo_relay = \fIboolean\fR
meillo@0 196
meillo@34 197 If this is set to false, mail with a return path that is not local and a destination
meillo@34 198 that is also not local will not be accepted via smtp and a 550 reply will be given.
meillo@34 199 Default is true.
meillo@0 200
meillo@34 201 Note that this will not protect you from spammers using open relays,
meillo@34 202 but from users unable to set their address in their mail clients.
meillo@0 203
meillo@0 204 .TP
meillo@34 205 \fBdo_queue = \fIboolean\fR
meillo@0 206
meillo@34 207 If this is set, mail will not be delivered immediately when accepted.
meillo@34 208 Same as calling masqmail with the \fB\-odq\fR option.
meillo@0 209
meillo@0 210 .TP
meillo@34 211 \fBonline_routes.\fIname\fR = \fIlist\fR
meillo@0 212
meillo@34 213 Replace \fIname\fR with a name to identify a connection.
meillo@34 214 Set this to a filename (or a list of filenames) for the special route configuration for that connection.
meillo@34 215 You will use that name to call masqmail with the \fB\-qo\fR option every time a
meillo@34 216 connection to your ISP is set up.
meillo@0 217
meillo@34 218 Example: Your ISP has the name FastNet.
meillo@34 219 Then you write the following line in the main configuration:
meillo@0 220
meillo@139 221 \fBonline_routes.FastNet\fR = \fI"/etc/masqmail/fastnet.route"\fR
meillo@0 222
meillo@34 223 \fI/etc/masqmail/fastnet.route\fR is the route configuration file, see \fBmasqmail.route(5)\fR.
meillo@34 224 As soon as a link to FastNet has been set up, you call masqmail \fB\-qo \fIFastNet\fR.
meillo@34 225 Masqmail will then read the specified file and send the mails.
meillo@0 226
meillo@0 227 .TP
meillo@34 228 \fBconnect_route.\fIname\fR = \fIlist\fR
meillo@0 229
meillo@34 230 Old name for \fBonline_routes\fR.
meillo@0 231
meillo@0 232 .TP
meillo@34 233 \fBlocal_net_route = \fIfile\fR
meillo@0 234
meillo@34 235 This is similar to \fBonline_routes.\fIname\fR but for the local net.
meillo@34 236 Recipient addresses that are in local_nets will be routed using this route configuration.
meillo@34 237 Main purpose is to define a mail server with mail_host in your local network.
meillo@34 238 In simple environments this can be left unset.
meillo@34 239 If unset, a default route configuration will be used.
meillo@0 240
meillo@0 241 .TP
meillo@34 242 \fBalias_file = \fIfile\fR
meillo@0 243
meillo@34 244 Set this to the location of your alias file.
meillo@34 245 If unset, no aliasing will be done.
meillo@0 246
meillo@0 247 .TP
meillo@34 248 \fBalias_local_caseless = \fIboolean\fR
meillo@0 249
meillo@0 250 If this is set, local parts in the alias file will be matched disregarding upper/lower case.
meillo@34 251
meillo@0 252 .TP
meillo@34 253 \fBpipe_fromline = \fIboolean\fR
meillo@0 254
meillo@34 255 If this is set, a from line will be prepended to the output stream whenever
meillo@34 256 a pipe command is called after an alias expansion.
meillo@34 257 Default is false.
meillo@0 258
meillo@0 259 .TP
meillo@34 260 \fBpipe_fromhack = \fIboolean\fR
meillo@0 261
meillo@34 262 If this is set, each line beginning with `From ' is replaced with `>From '
meillo@34 263 whenever a pipe command is called after an alias expansion.
meillo@34 264 You probably want this if you have set \fBpipe_fromline\fR above.
meillo@34 265 Default is false.
meillo@0 266
meillo@0 267 .TP
meillo@34 268 \fBmbox_default = \fIstring\fR
meillo@0 269
meillo@34 270 The default local delivery method.
meillo@34 271 Can be one of mbox, mda or maildir (the latter only if maildir support is enabled at compile time).
meillo@34 272 Default is mbox.
meillo@34 273 You can override this for each user by using the \fBmbox_users\fR, \fBmda_users\fR,
meillo@34 274 or \fBmaildir_users\fR options (see below).
meillo@0 275
meillo@0 276 .TP
meillo@34 277 \fBmbox_users = \fIlist\fR
meillo@0 278
meillo@0 279 A list of users which wish delivery to an mbox style mail folder.
meillo@34 280
meillo@0 281 .TP
meillo@34 282 \fBmda_users = \fIlist\fR
meillo@0 283
meillo@34 284 A list of users which wish local delivery to an mda.
meillo@34 285 You have to set \fBmda\fR (see below) as well.
meillo@0 286
meillo@0 287 .TP
meillo@34 288 \fBmaildir_users = \fIlist\fR
meillo@0 289
meillo@34 290 A list of users which wish delivery to a qmail style maildir.
meillo@34 291 The path to maildir is ~/Maildir/.
meillo@34 292 The maildir will be created if it does not exist.
meillo@0 293
meillo@0 294 .TP
meillo@34 295 \fBmda = \fIexpand string\fR
meillo@0 296
meillo@34 297 If you want local delivery to be transferred to an mda (Mail Delivery Agent),
meillo@34 298 set this to a command.
meillo@34 299 The argument will be expanded on delivery time,
meillo@34 300 you can use variables beginning with a dolloar sign `$', optionally enclosed in curly braces.
meillo@34 301 Variables you can use are:
meillo@0 302
meillo@34 303 uid - the unique message id.
meillo@34 304 This is not necessarily identical with the Message ID as given in the Message ID: header.
meillo@0 305
meillo@0 306 received_host - the host the mail was received from
meillo@0 307
meillo@34 308 ident - the ident, this is either the ident delivered by the ident protocol
meillo@34 309 or the user id of the sender if the message was received locally.
meillo@0 310
meillo@0 311 return_path_local - the local part of the return path (sender).
meillo@0 312
meillo@0 313 return_path_domain - the domain part of the return path (sender).
meillo@0 314
meillo@0 315 return_path - the complete return path (sender).
meillo@0 316
meillo@0 317 rcpt_local - the local part of the recipient.
meillo@0 318
meillo@0 319 rcpt_domain - the domain part of the recipient.
meillo@0 320
meillo@0 321 rcpt - the complete recipient address.
meillo@0 322
meillo@0 323 Example:
meillo@0 324
meillo@16 325 mda="/usr/bin/procmail \-Y \-d ${rcpt_local}"
meillo@0 326
meillo@34 327 For the mda, as for pipe commands, a few environment variables will be set as well.
meillo@34 328 See \fBmasqmail(8)\fR.
meillo@34 329 To use environment variables for the mda, the dollar sign `$' has to be escaped with a backslash,
meillo@34 330 otherwise they will be tried to be expanded with the internal variables.
meillo@34 331
meillo@0 332 .TP
meillo@34 333 \fBmda_fromline = \fIboolean\fR
meillo@0 334
meillo@34 335 If this is set, a from line will be prepended to the output stream whenever
meillo@34 336 a message is delivered to an mda.
meillo@34 337 Default is false.
meillo@0 338
meillo@0 339 .TP
meillo@34 340 \fBmda_fromhack = \fIboolean\fR
meillo@0 341
meillo@34 342 If this is set, each line beginning with `From ' is replaced with `>From '
meillo@34 343 whenever a message is delivered to an mda.
meillo@34 344 You probably want this if you have set \fBmda_fromline\fR above.
meillo@34 345 Default is false.
meillo@0 346
meillo@0 347 .TP
meillo@34 348 \fBonline_detect = \fIstring\fR
meillo@0 349
meillo@34 350 Defines the method masqmail uses to detect whether there is currently an online connection.
meillo@164 351 It can have the values \fIfile\fR or \fIpipe\fR.
meillo@0 352
meillo@112 353 When it is set to \fIfile\fR, masqmail first checks for the existence of \fBonline_file\fR
meillo@34 354 (see below) and if it exists, it reads it.
meillo@34 355 The content of the file should be the name of the current connection as defined
meillo@34 356 with \fBconnect_route.\fIname\fR (trailing whitespace is removed).
meillo@0 357
meillo@112 358 When it is set to \fIpipe\fR, masqmail calls the executable given by the
meillo@34 359 \fBonline_pipe\fR option (see below) and reads the current online status from its standard output.
meillo@0 360
meillo@34 361 No matter how masqmail detects the online status,
meillo@34 362 only messages that are accepted at online time will be delivered using the connection.
meillo@34 363 The spool still has to be emptied with masqmail \fB\-qo\fIconnection\fR.
meillo@0 364
meillo@0 365 .TP
meillo@34 366 \fBonline_file = \fIfile\fR
meillo@0 367
meillo@34 368 This is the name of the file checked for when masqmail determines whether it is online.
meillo@34 369 The file should only exist when there is currently a connection.
meillo@34 370 Create it in your ip-up script with e.g.
meillo@0 371
meillo@92 372 echo "connection-name" >/var/run/masqmail/masqmail-route
meillo@0 373
meillo@37 374 chmod 0644 /var/run/masqmail/masqmail-route
meillo@0 375
meillo@0 376 Do not forget to delete it in your ip-down script.
meillo@34 377
meillo@0 378 .TP
meillo@34 379 \fBonline_pipe = \fIfile\fR
meillo@0 380
meillo@34 381 This is the name of the executable which will be called to determine the online status.
meillo@34 382 This executable should just print the name of the current connection to
meillo@34 383 the standard output and return a zero status code.
meillo@34 384 masqmail assumes it is offline if the script returns with a non zero status.
meillo@34 385 Simple example:
meillo@0 386
meillo@0 387 #!/bin/sh
meillo@0 388
meillo@37 389 [ \-e /var/run/masqmail/masqmail-route ] || exit 1
meillo@0 390
meillo@37 391 cat /var/run/masqmail/masqmail-route
meillo@0 392
meillo@0 393 exit 0
meillo@0 394
meillo@129 395 Of course, instead of the example above you could as well use \fIfile\fR as
meillo@34 396 the online detection method, but you can do something more sophisticated.
meillo@34 397
meillo@158 398 \fIfile\fR must contain an absolute path to an executable program.
meillo@158 399 It can contain optional arguments.
meillo@0 400
meillo@158 401 Example: \fI/bin/echo foo\fR
meillo@158 402 (This tells masqmail to be always online with connection `foo'.)
meillo@158 403
meillo@164 404 For querying a masqdialer server
meillo@164 405 (= asking it whether a connection exists and what its name is)
meillo@164 406 use:
meillo@92 407
meillo@92 408 online_method=pipe
meillo@92 409
meillo@164 410 online_pipe="/usr/bin/mservdetect localhost 224"
meillo@92 411

meillo@34 435 \fBerrmsg_file = \fIfile\fR
meillo@0 436
meillo@34 437 Set this to a template which will be used to generate delivery failure reports.
meillo@34 438 Variable parts within the template begin with a dollar sign and are identical
meillo@34 439 to those which can be used as arguments for the mda command, see \fBmda\fR above.
meillo@34 440 Additional information can be included with @failed_rcpts, @msg_headers and @msg_body,
meillo@34 441 these must be at the beginning of a line and will be replaced with the list of the failed recipients,

meillo@0 456
meillo@34 457 Set this to a list of time intervals, at which delivery warnings
meillo@34 458 (starting with the receiving time of the message) shall be generated.
meillo@0 459
meillo@34 460 A warning will only be generated just after an attempt to deliver the mail
meillo@34 461 and if that attempt failed temporarily.
meillo@34 462 So a warning may be generated after a longer time, if there was no attempt before.
meillo@0 463
meillo@0 464 Default is "1h;4h;8h;1d;2d;3d"
meillo@34 465

meillo@34 467 \fBmax_defer_time\fR = \fItime\fR
meillo@0 468
meillo@34 469 This is the maximum time, in which a temporarily failed mail will be kept in the spool.
meillo@34 470 When this time is exceeded, it will be handled as a delivery failure,
meillo@34 471 and the message will be bounced.
meillo@0 472
meillo@34 473 The excedence of this time will only be noticed if the message was actually tried to be delivered.
meillo@34 474 If, for example, the message can only be delivered when online,
meillo@34 475 but you have not been online for that time, no bounce will be generated.
meillo@0 476
meillo@0 477 Default is 4d (4 days)

meillo@0 481
meillo@34 482 Replace \fIname\fR with a valid local or remote mail address.
meillo@0 483
meillo@44 484 If this option is set, then a copy of every mail,
meillo@44 485 that passes through the masqmail system will also be sent to the given mail address.
meillo@0 486
meillo@34 487 For example you can feed your mails into a program like hypermail
meillo@34 488 for archiving purpose by placing an appropriate pipe command in masqmail.alias

meillo@117 491 \fBmax_msg_size\fR = \fIbytes\fR
meillo@117 492
meillo@117 493 This option sets the maximum size in bytes masqmail will accept for delivery.
meillo@117 494 This value is advertised to the SMTP client by the `SIZE' message during SMTP
meillo@117 495 session setup.
meillo@117 496 Clients pretending to send, or actually send,
meillo@117 497 more than \fIbytes\fR will get a 552 error message.
meillo@117 498
meillo@120 499 `0' means no fixed maximum size limit is in force.
meillo@120 500
