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 val 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 before 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 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 \fBmail_dir = \fIfile\fR
68 The directory where local mail is stored, usually \fI/var/spool/mail\fR or \fI/var/mail\fR.
70 .TP
71 \fBspool_dir = \fIfile\fR
73 The directory where masqmail stores its spool files (and later also other stuff).
74 It must have a subdirectory \fIinput\fR.
75 Masqmail needs read and write permissions for this directory.
76 I suggest to use \fI/var/spool/masqmail\fR.
78 .TP
79 \fBhost_name = \fIstring\fR
81 This is used in different places: Masqmail identifies itself in the greeting banner
82 on incoming connections and in the HELO/EHLO command for outgoing connections with this name,
83 it is used in the Received: header and to qualify the sender of a locally originating message.
85 If the string begins with a slash `/', it it assumed that it is a filename,
86 and the first line of this file will be used.
87 Usually this will be `/etc/mailname' to make masqmail conform to Debian policies.
89 It is not used to find whether an address is local. Use \fBlocal_hosts\fR for that.
91 .TP
92 \fBremote_port = \fIn\fR
94 The remote port number to be used. This defaults to port 25.
96 This option is deprecated.
97 Use \fBhost_name\fR in the route configuration instead.
98 See \fBmasqmail.route(5)\fR.
100 .TP
101 \fBlocal_hosts = \fIlist\fR
103 A semicolon `;' separated list of hostnames which are considered local.
104 Normally you set it to "localhost;foo;foo.bar.com" if your host has the
105 fully qualified domain name `foo.bar.com'.
107 .TP
108 \fBlocal_nets = \fIlist\fR
110 A semicolon `;' separated list of hostnames which are on the `local' net.
111 Delivery to these hosts is attempted immediately.
112 You can use patterns with `*', e.g. "*.bar.com".
114 .TP
115 \fBlocal_addresses = \fIlist\fR
117 A semicolon `;' separated list of fully qualified email-addresses which are
118 considered local although their domain name part is not in the list of \fBlocal_hosts\fR.
120 For example: There are two people working at your LAN: person1@yourdomain and person2@yourdomain.
121 But there are other persons @yourdomain which are NOT local.
122 So you can not put yourdomain to the list of local_hosts.
123 If person1 now wants to write to person2@yourdomain and this mail should not leave the LAN then you can put
125 local_addresses = "person1@yourdomain;person2@yourdomain"
127 to your masqmail.conf.
129 .TP
130 \fBnot_local_addresses = \fIlist\fR
132 A semicolon `;' separated list of fully qualified email-addresses which are
133 considered not local although their domain name part is in the list of \fBlocal_hosts\fR.
135 This is the opposite of the previous case.
136 The majority of addresses of a specific domain are local.
137 But some users are not.
138 With this option you can easily exclude these users.
140 Example:
142 local_hosts = "localhost;myhost;mydomain.net"
144 not_local_addresses = "eric@mydomain.net"
146 .TP
147 \fBlisten_addresses = \fIlist\fR
149 A semicolon `;' separated list of interfaces on which connections will be accepted.
150 An interface ist defined by a hostname, optionally followed by a colon `:' and a number for the port.
151 If this is left out, port 25 will be used.
153 You can set this to "localhost:25;foo:25" if your hostname is `foo'.
155 Note that the names are resolved to IP addreses.
156 If your host has different names which resolve to the same IP,
157 use only one of them, otherwise you will get an error message.
159 .TP
160 \fBdo_save_envelope_to = \fIboolean\fR
162 If this is set to true, a possibly existing Envelope-to: header in an incoming mail
163 which is received via either pop3 or smtp will be saved as an X-Orig-Envelope-to: header.
165 This is useful if you retrieve mail from a pop3 server with either masqmail or fetchmail,
166 and the server supports Envelope-to: headers,
167 and you want to make use of those with a mail filtering tool, e.g. procmail.
168 It cannot be preserved because masqmail sets such a header by itself.
170 Default is false.
172 .TP
173 \fBdo_relay = \fIboolean\fR
175 If this is set to false, mail with a return path that is not local and a destination
176 that is also not local will not be accepted via smtp and a 550 reply will be given.
177 Default is true.
179 Note that this will not protect you from spammers using open relays,
180 but from users unable to set their address in their mail clients.
182 .TP
183 \fBdo_queue = \fIboolean\fR
185 If this is set, mail will not be delivered immediately when accepted.
186 Same as calling masqmail with the \fB\-odq\fR option.
188 .TP
189 \fBonline_routes.\fIname\fR = \fIlist\fR
191 Replace \fIname\fR with a name to identify a connection.
192 Set this to a filename (or a list of filenames) for the special route configuration for that connection.
193 You will use that name to call masqmail with the \fB\-qo\fR option every time a
194 connection to your ISP is set up.
196 Example: Your ISP has the name FastNet.
197 Then you write the following line in the main configuration:
199 \fBonline_routes.FastNet\fR = \fI"/etc/masqmail/fastnet.route"\fR
201 \fI/etc/masqmail/fastnet.route\fR is the route configuration file, see \fBmasqmail.route(5)\fR.
202 As soon as a link to FastNet has been set up, you call masqmail \fB\-qo \fIFastNet\fR.
203 Masqmail will then read the specified file and send the mails.
205 .TP
206 \fBconnect_route.\fIname\fR = \fIlist\fR
208 Old name for \fBonline_routes\fR.
210 .TP
211 \fBlocal_net_route = \fIfile\fR
213 This is similar to \fBonline_routes.\fIname\fR but for the local net.
214 Recipient addresses that are in local_nets will be routed using this route configuration.
215 Main purpose is to define a mail server with mail_host in your local network.
216 In simple environments this can be left unset.
217 If unset, a default route configuration will be used.
219 .TP
220 \fBalias_file = \fIfile\fR
222 Set this to the location of your alias file.
223 If unset, no aliasing will be done.
225 .TP
226 \fBalias_local_caseless = \fIboolean\fR
228 If this is set, local parts in the alias file will be matched disregarding upper/lower case.
230 .TP
231 \fBpipe_fromline = \fIboolean\fR
233 If this is set, a from line will be prepended to the output stream whenever
234 a pipe command is called after an alias expansion.
235 Default is false.
237 .TP
238 \fBpipe_fromhack = \fIboolean\fR
240 If this is set, each line beginning with `From ' is replaced with `>From '
241 whenever a pipe command is called after an alias expansion.
242 You probably want this if you have set \fBpipe_fromline\fR above.
243 Default is false.
245 .TP
246 \fBmbox_default = \fIstring\fR
248 The default local delivery method.
249 Can be one of mbox, mda or maildir (the latter only if maildir support is enabled at compile time).
250 Default is mbox.
251 You can override this for each user by using the \fBmbox_users\fR, \fBmda_users\fR,
252 or \fBmaildir_users\fR options (see below).
254 .TP
255 \fBmbox_users = \fIlist\fR
257 A list of users which wish delivery to an mbox style mail folder.
259 .TP
260 \fBmda_users = \fIlist\fR
262 A list of users which wish local delivery to an mda.
263 You have to set \fBmda\fR (see below) as well.
265 .TP
266 \fBmaildir_users = \fIlist\fR
268 A list of users which wish delivery to a qmail style maildir.
269 The path to maildir is ~/Maildir/.
270 The maildir will be created if it does not exist.
272 .TP
273 \fBmda = \fIexpand string\fR
275 If you want local delivery to be transferred to an mda (Mail Delivery Agent),
276 set this to a command.
277 The argument will be expanded on delivery time,
278 you can use variables beginning with a dolloar sign `$', optionally enclosed in curly braces.
279 Variables you can use are:
281 uid - the unique message id.
282 This is not necessarily identical with the Message ID as given in the Message ID: header.
284 received_host - the host the mail was received from
286 ident - the ident, this is either the ident delivered by the ident protocol
287 or the user id of the sender if the message was received locally.
289 return_path_local - the local part of the return path (sender).
291 return_path_domain - the domain part of the return path (sender).
293 return_path - the complete return path (sender).
295 rcpt_local - the local part of the recipient.
297 rcpt_domain - the domain part of the recipient.
299 rcpt - the complete recipient address.
301 Example:
303 mda="/usr/bin/procmail \-Y \-d ${rcpt_local}"
305 For the mda, as for pipe commands, a few environment variables will be set as well.
306 See \fBmasqmail(8)\fR.
307 To use environment variables for the mda, the dollar sign `$' has to be escaped with a backslash,
308 otherwise they will be tried to be expanded with the internal variables.
310 .TP
311 \fBmda_fromline = \fIboolean\fR
313 If this is set, a from line will be prepended to the output stream whenever
314 a message is delivered to an mda.
315 Default is false.
317 .TP
318 \fBmda_fromhack = \fIboolean\fR
320 If this is set, each line beginning with `From ' is replaced with `>From '
321 whenever a message is delivered to an mda.
322 You probably want this if you have set \fBmda_fromline\fR above.
323 Default is false.
325 .TP
326 \fBonline_detect = \fIstring\fR
328 Defines the method masqmail uses to detect whether there is currently an online connection.
329 It can have the values \fBfile\fR, \fBpipe\fR, or \fBmserver\fR.
331 When it is set to \fBfile\fR, masqmail first checks for the existence of \fBonline_file\fR
332 (see below) and if it exists, it reads it.
333 The content of the file should be the name of the current connection as defined
334 with \fBconnect_route.\fIname\fR (trailing whitespace is removed).
336 When it is set to \fBpipe\fR, masqmail calls the executable given by the
337 \fBonline_pipe\fR option (see below) and reads the current online status from its standard output.
339 When it is set to \fBmserver\fR, masqmail connects to the masqdialer server
340 using the value of \fBmserver_iface\fR and asks it whether a connection exists and for the name,
341 which should be the name of the current connection as defined with \fBconnect_route.\fIname\fR.
343 No matter how masqmail detects the online status,
344 only messages that are accepted at online time will be delivered using the connection.
345 The spool still has to be emptied with masqmail \fB\-qo\fIconnection\fR.
347 .TP
348 \fBonline_file = \fIfile\fR
350 This is the name of the file checked for when masqmail determines whether it is online.
351 The file should only exist when there is currently a connection.
352 Create it in your ip-up script with e.g.
354 echo \-n <name> > /tmp/connect_route
356 chmod 0644 /tmp/connect_route
358 Do not forget to delete it in your ip-down script.
360 .TP
361 \fBonline_pipe = \fIfile\fR
363 This is the name of the executable which will be called to determine the online status.
364 This executable should just print the name of the current connection to
365 the standard output and return a zero status code.
366 masqmail assumes it is offline if the script returns with a non zero status.
367 Simple example:
369 #!/bin/sh
371 [ \-e /tmp/connect_route ] || exit 1
373 cat /tmp/connect_route
375 exit 0
377 Of course, instead of the example above you could as well use \fBfile\fR as
378 the online detection method, but you can do something more sophisticated.
380 .TP
381 \fBmserver_iface = \fIinterface\fR
383 The interface the masqdialer server is listening to.
384 Usually this will be "localhost:224" if mserver is running on the same host as masqmail.
385 But using this option, you can also let masqmail run on another host by setting
386 \fBmserver_iface\fR to another hostname, e.g. "foo:224".
388 .TP
389 \fBget.\fIname\fR = \fIfile\fR
391 Replace \fIname\fR with a name to identify a get configuration.
392 Set this to a filename for the get configuration.
393 These files will be used to retrieve mail when called with the \-g option.
395 .TP
396 \fBonline_gets.\fIname\fR = \fIlist\fR
398 Replace \fIname\fR with a name to identify an online configuration.
399 Set this to a filename (or a list of filenames) for the get configuration.
400 These files will be used to retrieve mail when called with the \-go option.
402 .TP
403 \fBident_trusted_nets = \fIlist\fR
405 \fIlist\fR is a list of networks of the form a.b.c.d/e (e.g. 192.168.1.0/24),
406 from which the ident given by the ident protocol will be trusted,
407 so a user can delete his mail from the queue if the ident is identical to his login name.
409 .TP
410 \fBerrmsg_file = \fIfile\fR
412 Set this to a template which will be used to generate delivery failure reports.
413 Variable parts within the template begin with a dollar sign and are identical
414 to those which can be used as arguments for the mda command, see \fBmda\fR above.
415 Additional information can be included with @failed_rcpts, @msg_headers and @msg_body,
416 these must be at the beginning of a line and will be replaced with the list of the failed recipients,
417 the message headers and the message body of the failed message.
419 Default is /usr/share/masqmail/tpl/failmsg.tpl.
421 .TP
422 \fBwarnmsg_file = \fIfile\fR
424 Set this to a template which will be used to generate delivery warning reports.
425 It uses the same mechanisms for variables as \fBerrmsg_file\fR, see above.
427 Default is /usr/share/masqmail/tpl/warnmsg.tpl.
429 .TP
430 \fBwarn_intervals\fR = \fIlist\fR
432 Set this to a list of time intervals, at which delivery warnings
433 (starting with the receiving time of the message) shall be generated.
435 A warning will only be generated just after an attempt to deliver the mail
436 and if that attempt failed temporarily.
437 So a warning may be generated after a longer time, if there was no attempt before.
439 Default is "1h;4h;8h;1d;2d;3d"
441 .TP
442 \fBmax_defer_time\fR = \fItime\fR
444 This is the maximum time, in which a temporarily failed mail will be kept in the spool.
445 When this time is exceeded, it will be handled as a delivery failure,
446 and the message will be bounced.
448 The excedence of this time will only be noticed if the message was actually tried to be delivered.
449 If, for example, the message can only be delivered when online,
450 but you have not been online for that time, no bounce will be generated.
452 Default is 4d (4 days)
454 .TP
455 \fBlog_user = \fIname\fR
457 Replace \fIname\fR with a valid local or remote mail address.
459 If this option is not empty, then a copy of every mail,
460 that passes trough the masqmail system will also be sent to the given mail address.
462 For example you can feed your mails into a program like hypermail
463 for archiving purpose by placing an appropriate pipe command in masqmail.alias
