3 .SH NAME
4 masqmail.conf \- masqmail configuration file
7 .SH DESCRIPTION
9 This man page describes the syntax of the main configuration file of masqmail.
10 Its usual location is \fI/etc/masqmail/masqmail.conf\fR
12 The configuration consists of lines of the form
14 \fBval\fR = \fIexpression\fR
16 Where \fBval\fR is a variable name and \fIexpression\fR a string,
17 which can be quoted with double quotes `"'.
18 If the expression is on multiple lines or contains characters other than letters,
19 digits or the characters `.', `-', `_', `/', ';', '@', ':', it must be quoted.
20 You can use quotes inside quotes by escaping them with a backslash.
22 Each \fBval\fP has a type, which can be boolean, numeric, string or list.
23 A boolean variable can be set with one of the values `on', `yes', and `true' or `off', `no' and `false'.
24 List items are separated with semicolons `;'.
25 For some values, patterns (like `*',`?') can be used.
26 The spaces in front of and after the equal sign `=' are optional.
28 Most lists (exceptions: \fBlocal_hosts\fR, \fBlocal_nets\fR, \fBlisten_addresses\fR,
29 \fBonline_routes\fR, and \fBonline_gets\fR) accept files.
30 These will be recognized by a leading slash `/'.
31 The contents of these files will be included at the position of the file name,
32 there can be items or other files before and after the file entry.
33 The format of the files is different though, within these files each entry is on another line
34 and the entries are not separated by semicolons.
35 This makes it easy to include large lists which are common in different configuration files,
36 so they do not have to appear in every configuration file.
38 Blank lines and lines starting with a hash `#' are ignored.
41 .SH OPTIONS
43 .TP
44 \fBrun_as_user = \fIboolean\fR
46 If this is set, masqmail runs with the user id of the user who invoked it and never changes it.
47 This is for debugging purposes only.
48 If the user is not root, masqmail will not be able to listen on a port < 1024
49 and will not be able to deliver local mail to others than the user.
51 .TP
52 \fBuse_syslog = \fIboolean\fR
54 If this is set, masqmail uses syslogd for logging.
55 It uses facility MAIL.
56 You still have to set \fBlog_dir\fR for debug files.
58 .TP
59 \fBdebug_level = \fIn\fR
61 Set the debug level.
62 Valid values are 0 to 6, increasing it further makes no difference.
63 Be careful if you set this as high as 5 or higher, the logs may very soon fill your hard drive.
65 .TP
66 \fBlog_dir = \fIfile\fR
68 The directory where logs are stored, if syslog is not used.
69 Debug files are always stored in this directory if debugging is enabled.
70 \fIfile\fR must be an absolute path.
72 Default: \fI/var/log/masqmail\fR
74 .TP
75 \fBmail_dir = \fIfile\fR
77 The directory where local mail is stored, usually \fI/var/spool/mail\fR or \fI/var/mail\fR.
78 \fIfile\fR must be an absolute path.
80 Default: \fI/var/mail\fR
82 .TP
83 \fBspool_dir = \fIfile\fR
85 The directory where masqmail stores its spool files (and later also other stuff).
86 It must have a subdirectory \fIinput\fR.
87 Masqmail needs read and write permissions for this directory.
88 \fIfile\fR must be an absolute path.
90 Default: \fI/var/spool/masqmail\fR
92 .TP
93 \fBlock_dir = \fIfile\fR
95 The directory where masqmail stores its lock files.
96 Masqmail needs read and write permissions for this directory.
97 By default it is a directory ``lock'' inside of \fIspool_dir\fP.
98 \fIfile\fR must be an absolute path.
100 .TP
101 \fBhost_name = \fIstring\fR
103 This is used in different places: Masqmail identifies itself in the greeting banner
104 on incoming connections and in the HELO/EHLO command for outgoing connections with this name,
105 it is used in the Received: header and to qualify the sender of a locally originating message.
107 If the string begins with a slash `/', it it assumed that it is a filename,
108 and the first line of this file will be used.
109 Usually this will be `/etc/mailname' to make masqmail conform to Debian policies.
111 It is not used to find whether an address is local. Use \fBlocal_hosts\fR for that.
113 Default: none; \fBhost_name\fP MUST be set in the config file
115 .TP
116 \fBlocal_hosts = \fIlist\fR
118 A semicolon `;' separated list of hostnames which are considered local.
119 Normally you should set it to "localhost;foo;foo.bar.com" if your host has the
120 fully qualified domain name `foo.bar.com'.
122 Default: localhost ; <value of \fBhost_name\fR cut at the first dot> ; <value of \fBhost_name\fR>
124 Example: \fIlocalhost;foo;foo.example.org\fR
125 (if you have set \fBhost_name\fR to \fIfoo.example.org\fR)
127 .TP
128 \fBlocal_nets = \fIlist\fR
130 A semicolon `;' separated list of hostnames which are on the `local' net.
131 Delivery to these hosts is attempted immediately.
132 You can use patterns with `*', e.g. "*.bar.com".
134 .TP
135 \fBlocal_addresses = \fIlist\fR
137 A semicolon `;' separated list of fully qualified email-addresses which are
138 considered local although their domain name part is not in the list of \fBlocal_hosts\fR.
140 For example: There are two people working at your LAN: person1@yourdomain and person2@yourdomain.
141 But there are other persons @yourdomain which are NOT local.
142 So you can not put yourdomain to the list of local_hosts.
143 If person1 now wants to write to person2@yourdomain and this mail should not leave the LAN then you can put
145 local_addresses = "person1@yourdomain;person2@yourdomain"
147 to your masqmail.conf.
149 .TP
150 \fBnot_local_addresses = \fIlist\fR
152 A semicolon `;' separated list of fully qualified email-addresses which are
153 considered not local although their domain name part is in the list of \fBlocal_hosts\fR.
155 This is the opposite of the previous case.
156 The majority of addresses of a specific domain are local.
157 But some users are not.
158 With this option you can easily exclude these users.
160 Example:
162 local_hosts = "localhost;myhost;mydomain.net"
164 not_local_addresses = "eric@mydomain.net"
166 .TP
167 \fBlisten_addresses = \fIlist\fR
169 A semicolon `;' separated list of interfaces on which connections will be accepted.
170 An interface ist defined by a hostname, optionally followed by a colon `:' and a number for the port.
171 If this is left out, port 25 will be used.
173 You can set this to "localhost:25;foo:25" if your hostname is `foo'.
175 Note that the names are resolved to IP addreses.
176 If your host has different names which resolve to the same IP,
177 use only one of them, otherwise you will get an error message.
179 Default: \fIlocalhost:25\fR (i.e. only local processes can connect)
181 .TP
182 \fBdo_save_envelope_to = \fIboolean\fR
184 If this is set to true, a possibly existing Envelope-to: header in an incoming mail
185 which is received via either pop3 or smtp will be saved as an X-Orig-Envelope-to: header.
187 This is useful if you retrieve mail from a pop3 server with either masqmail or fetchmail,
188 and the server supports Envelope-to: headers,
189 and you want to make use of those with a mail filtering tool, e.g. procmail.
190 It cannot be preserved because masqmail sets such a header by itself.
192 Default is false.
194 .TP
195 \fBdo_relay = \fIboolean\fR
197 If this is set to false, mail with a return path that is not local and a destination
198 that is also not local will not be accepted via smtp and a 550 reply will be given.
199 Default is true.
201 Note that this will not protect you from spammers using open relays,
202 but from users unable to set their address in their mail clients.
204 .TP
205 \fBdo_queue = \fIboolean\fR
207 If this is set, mail will not be delivered immediately when accepted.
208 Same as calling masqmail with the \fB\-odq\fR option.
210 .TP
211 \fBonline_routes.\fIname\fR = \fIlist\fR
213 Replace \fIname\fR with a name to identify a connection.
214 Set this to a filename (or a list of filenames) for the special route configuration for that connection.
215 You will use that name to call masqmail with the \fB\-qo\fR option every time a
216 connection to your ISP is set up.
218 Example: Your ISP has the name FastNet.
219 Then you write the following line in the main configuration:
221 \fBonline_routes.FastNet\fR = \fI"/etc/masqmail/fastnet.route"\fR
223 \fI/etc/masqmail/fastnet.route\fR is the route configuration file, see \fBmasqmail.route(5)\fR.
224 As soon as a link to FastNet has been set up, you call masqmail \fB\-qo \fIFastNet\fR.
225 Masqmail will then read the specified file and send the mails.
227 .TP
228 \fBconnect_route.\fIname\fR = \fIlist\fR
230 Old name for \fBonline_routes\fR.
232 .TP
233 \fBlocal_net_route = \fIfile\fR
235 This is similar to \fBonline_routes.\fIname\fR but for the local net.
236 Recipient addresses that are in local_nets will be routed using this route configuration.
237 Main purpose is to define a mail server with mail_host in your local network.
238 In simple environments this can be left unset.
239 If unset, a default route configuration will be used.
241 .TP
242 \fBalias_file = \fIfile\fR
244 Set this to the location of your alias file.
245 If unset, no aliasing will be done.
247 .TP
248 \fBalias_local_caseless = \fIboolean\fR
250 If this is set, local parts in the alias file will be matched disregarding upper/lower case.
252 .TP
253 \fBpipe_fromline = \fIboolean\fR
255 If this is set, a from line will be prepended to the output stream whenever
256 a pipe command is called after an alias expansion.
257 Default is false.
259 .TP
260 \fBpipe_fromhack = \fIboolean\fR
262 If this is set, each line beginning with `From ' is replaced with `>From '
263 whenever a pipe command is called after an alias expansion.
264 You probably want this if you have set \fBpipe_fromline\fR above.
265 Default is false.
267 .TP
268 \fBmbox_default = \fIstring\fR
270 The default local delivery method.
271 Can be one of mbox, mda or maildir (the latter only if maildir support is enabled at compile time).
272 Default is mbox.
273 You can override this for each user by using the \fBmbox_users\fR, \fBmda_users\fR,
274 or \fBmaildir_users\fR options (see below).
276 .TP
277 \fBmbox_users = \fIlist\fR
279 A list of users which wish delivery to an mbox style mail folder.
281 .TP
282 \fBmda_users = \fIlist\fR
284 A list of users which wish local delivery to an mda.
285 You have to set \fBmda\fR (see below) as well.
287 .TP
288 \fBmaildir_users = \fIlist\fR
290 A list of users which wish delivery to a qmail style maildir.
291 The path to maildir is ~/Maildir/.
292 The maildir will be created if it does not exist.
294 .TP
295 \fBmda = \fIexpand string\fR
297 If you want local delivery to be transferred to an mda (Mail Delivery Agent),
298 set this to a command.
299 The argument will be expanded on delivery time,
300 you can use variables beginning with a dolloar sign `$', optionally enclosed in curly braces.
301 Variables you can use are:
303 uid - the unique message id.
304 This is not necessarily identical with the Message ID as given in the Message ID: header.
306 received_host - the host the mail was received from
308 ident - the ident, this is either the ident delivered by the ident protocol
309 or the user id of the sender if the message was received locally.
311 return_path_local - the local part of the return path (sender).
313 return_path_domain - the domain part of the return path (sender).
315 return_path - the complete return path (sender).
317 rcpt_local - the local part of the recipient.
319 rcpt_domain - the domain part of the recipient.
321 rcpt - the complete recipient address.
323 Example:
325 mda="/usr/bin/procmail \-Y \-d ${rcpt_local}"
327 For the mda, as for pipe commands, a few environment variables will be set as well.
328 See \fBmasqmail(8)\fR.
329 To use environment variables for the mda, the dollar sign `$' has to be escaped with a backslash,
330 otherwise they will be tried to be expanded with the internal variables.
332 .TP
333 \fBmda_fromline = \fIboolean\fR
335 If this is set, a from line will be prepended to the output stream whenever
336 a message is delivered to an mda.
337 Default is false.
339 .TP
340 \fBmda_fromhack = \fIboolean\fR
342 If this is set, each line beginning with `From ' is replaced with `>From '
343 whenever a message is delivered to an mda.
344 You probably want this if you have set \fBmda_fromline\fR above.
345 Default is false.
347 .TP
348 \fBonline_detect = \fIstring\fR
350 Defines the method masqmail uses to detect whether there is currently an online connection.
351 It can have the values \fIfile\fR or \fIpipe\fR.
353 When it is set to \fIfile\fR, masqmail first checks for the existence of \fBonline_file\fR
354 (see below) and if it exists, it reads it.
355 The content of the file should be the name of the current connection as defined
356 with \fBconnect_route.\fIname\fR (trailing whitespace is removed).
358 When it is set to \fIpipe\fR, masqmail calls the executable given by the
359 \fBonline_pipe\fR option (see below) and reads the current online status from its standard output.
361 No matter how masqmail detects the online status,
362 only messages that are accepted at online time will be delivered using the connection.
363 The spool still has to be emptied with masqmail \fB\-qo\fIconnection\fR.
365 .TP
366 \fBonline_file = \fIfile\fR
368 This is the name of the file checked for when masqmail determines whether it is online.
369 The file should only exist when there is currently a connection.
370 Create it in your ip-up script with e.g.
372 echo "connection-name" >/var/run/masqmail/masqmail-route
374 chmod 0644 /var/run/masqmail/masqmail-route
376 Do not forget to delete it in your ip-down script.
378 .TP
379 \fBonline_pipe = \fIfile\fR
381 This is the name of the executable which will be called to determine the online status.
382 This executable should just print the name of the current connection to
383 the standard output and return a zero status code.
384 masqmail assumes it is offline if the script returns with a non zero status.
385 Simple example:
387 #!/bin/sh
389 [ \-e /var/run/masqmail/masqmail-route ] || exit 1
391 cat /var/run/masqmail/masqmail-route
393 exit 0
395 Of course, instead of the example above you could as well use \fIfile\fR as
396 the online detection method, but you can do something more sophisticated.
398 \fIfile\fR must contain an absolute path to an executable program.
399 It can contain optional arguments.
401 Example: \fI/bin/echo foo\fR
402 (This tells masqmail to be always online with connection `foo'.)
404 For querying a masqdialer server
405 (= asking it whether a connection exists and what its name is)
406 use:
408 online_method=pipe
410 online_pipe="/usr/bin/mservdetect localhost 224"
413 .TP
414 \fBget.\fIname\fR = \fIfile\fR
416 Replace \fIname\fR with a name to identify a get configuration.
417 Set this to a filename for the get configuration.
418 These files will be used to retrieve mail when called with the \-g option.
420 .TP
421 \fBonline_gets.\fIname\fR = \fIlist\fR
423 Replace \fIname\fR with a name to identify an online configuration.
424 Set this to a filename (or a list of filenames) for the get configuration.
425 These files will be used to retrieve mail when called with the \-go option.
427 .TP
428 \fBident_trusted_nets = \fIlist\fR
430 \fIlist\fR is a list of networks of the form a.b.c.d/e (e.g. 192.168.1.0/24),
431 from which the ident given by the ident protocol will be trusted,
432 so a user can delete his mail from the queue if the ident is identical to his login name.
434 .TP
435 \fBerrmsg_file = \fIfile\fR
437 Set this to a template which will be used to generate delivery failure reports.
438 Variable parts within the template begin with a dollar sign and are identical
439 to those which can be used as arguments for the mda command, see \fBmda\fR above.
440 Additional information can be included with @failed_rcpts, @msg_headers and @msg_body,
441 these must be at the beginning of a line and will be replaced with the list of the failed recipients,
442 the message headers and the message body of the failed message.
444 Default is /usr/share/masqmail/tpl/failmsg.tpl.
446 .TP
447 \fBwarnmsg_file = \fIfile\fR
449 Set this to a template which will be used to generate delivery warning reports.
450 It uses the same mechanisms for variables as \fBerrmsg_file\fR, see above.
452 Default is /usr/share/masqmail/tpl/warnmsg.tpl.
454 .TP
455 \fBwarn_intervals\fR = \fIlist\fR
457 Set this to a list of time intervals, at which delivery warnings
458 (starting with the receiving time of the message) shall be generated.
460 A warning will only be generated just after an attempt to deliver the mail
461 and if that attempt failed temporarily.
462 So a warning may be generated after a longer time, if there was no attempt before.
464 Default is "1h;4h;8h;1d;2d;3d"
466 .TP
467 \fBmax_defer_time\fR = \fItime\fR
469 This is the maximum time, in which a temporarily failed mail will be kept in the spool.
470 When this time is exceeded, it will be handled as a delivery failure,
471 and the message will be bounced.
473 The excedence of this time will only be noticed if the message was actually tried to be delivered.
474 If, for example, the message can only be delivered when online,
475 but you have not been online for that time, no bounce will be generated.
477 Default is 4d (4 days)
479 .TP
480 \fBlog_user = \fIname\fR
482 Replace \fIname\fR with a valid local or remote mail address.
484 If this option is set, then a copy of every mail,
485 that passes through the masqmail system will also be sent to the given mail address.
487 For example you can feed your mails into a program like hypermail
488 for archiving purpose by placing an appropriate pipe command in masqmail.alias
490 .TP
491 \fBmax_msg_size\fR = \fIbytes\fR
493 This option sets the maximum size in bytes masqmail will accept for delivery.
494 This value is advertised to the SMTP client by the `SIZE' message during SMTP
495 session setup.
496 Clients pretending to send, or actually send,
497 more than \fIbytes\fR will get a 552 error message.
499 `0' means no fixed maximum size limit is in force.
501 Default is 0 (= unlimited).
503 .TP
504 \fBdefer_all\fR = \fIboolean\fR
506 If set to true, masqmail replies with ``421 service temporarily unavailable''
507 to any SMTP request and shuts the connection down.
508 Note: This option is for debugging purposes only.
510 Default: false
