modes are now enforced exclusive
Other MTAs (exim, postfix) are more relaxing, but as combinations
of exclusive modes are senseless we behave more obvious if we
fail early. This makes understanding the behavior easier too.

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 and \fBonline_routes\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_addresses = \fIlist\fR
130 A semicolon `;' separated list of fully qualified email-addresses which are
131 considered local although their domain name part is not in the list of \fBlocal_hosts\fR.
132 This list can be seen as an addition to \fBlocal_hosts\fP.
134 For example: There are two people working at your LAN: person1@yourdomain and person2@yourdomain.
135 But there are other persons @yourdomain which are NOT local.
136 So you can not put yourdomain to the list of local_hosts.
137 If person1 now wants to write to person2@yourdomain and this mail should not leave the LAN then you can put
139 local_addresses = "person1@yourdomain;person2@yourdomain"
141 to your masqmail.conf.
143 .TP
144 \fBnot_local_addresses = \fIlist\fR
146 A semicolon `;' separated list of fully qualified email-addresses which are
147 considered not local although their domain name part is in the list of \fBlocal_hosts\fR.
148 This list can be seen as a substraction to \fBlocal_hosts\fP.
150 This is the opposite of the previous case.
151 The majority of addresses of a specific domain are local.
152 But some users are not.
153 With this option you can easily exclude these users.
155 Example:
157 local_hosts = "localhost;myhost;mydomain.net"
159 not_local_addresses = "eric@mydomain.net"
161 .TP
162 \fBlocal_nets = \fIlist\fR
164 A semicolon `;' separated list of hostnames which are on the `local' net.
165 Delivery to these hosts is attempted immediately.
166 You can use patterns with `*', e.g. "*.bar.com".
168 .TP
169 \fBlisten_addresses = \fIlist\fR
171 A semicolon `;' separated list of interfaces on which connections will be accepted.
172 An interface ist defined by a hostname, optionally followed by a colon `:' and a number for the port.
173 If this is left out, port 25 will be used.
175 You can set this to "localhost:25;foo:25" if your hostname is `foo'.
177 Note that the names are resolved to IP addreses.
178 If your host has different names which resolve to the same IP,
179 use only one of them, otherwise you will get an error message.
181 Default: \fI127.0.0.1:25\fR (i.e. only local processes can connect)
183 .TP
184 \fBdo_save_envelope_to = \fIboolean\fR
186 If this is set to true, a possibly existing Envelope-to: header in an incoming mail
187 which is received via either pop3 or smtp will be saved as an X-Orig-Envelope-to: header.
189 This is useful if you retrieve mail from a pop3 server with fetchmail,
190 and the server supports Envelope-to: headers,
191 and you want to make use of those with a mail filtering tool, e.g. procmail.
192 It cannot be preserved because masqmail sets such a header by itself.
194 Default is false.
196 .TP
197 \fBdo_relay = \fIboolean\fR
199 If this is set to false, mail with a return path that is not local and a destination
200 that is also not local will not be accepted via smtp and a 550 reply will be given.
201 Default is true.
203 Note that this will not protect you from spammers using open relays,
204 but from users unable to set their address in their mail clients.
206 .TP
207 \fBdo_queue = \fIboolean\fR
209 If this is set, mail will not be delivered immediately when accepted.
210 Same as calling masqmail with the \fB\-odq\fR option.
212 .TP
213 \fBonline_routes.\fIname\fR = \fIlist\fR
215 Replace \fIname\fR with a name to identify a connection.
216 Set this to a filename (or a list of filenames) for the special route configuration for that connection.
217 You will use that name to call masqmail with the \fB\-qo\fR option every time a
218 connection to your ISP is set up.
220 Example: Your ISP has the name FastNet.
221 Then you write the following line in the main configuration:
223 \fBonline_routes.FastNet\fR = \fI"/etc/masqmail/fastnet.route"\fR
225 \fI/etc/masqmail/fastnet.route\fR is the route configuration file, see \fBmasqmail.route(5)\fR.
226 As soon as a link to FastNet has been set up, you call masqmail \fB\-qo \fIFastNet\fR.
227 Masqmail will then read the specified file and send the mails.
229 .TP
230 \fBconnect_route.\fIname\fR = \fIlist\fR
232 Old name for \fBonline_routes\fR.
234 .TP
235 \fBlocal_net_route = \fIfile\fR
237 This is similar to \fBonline_routes.\fIname\fR but used for delilvery to the local net.
238 Recipient addresses that are in local_nets will be routed using this route configuration.
239 Main purpose is to define a mail server with mail_host in your local network.
240 In simple environments this can be left unset.
241 If unset, a default route configuration (named ``default local_net_route'') will be used.
243 .TP
244 \fBalias_file = \fIfile\fR
246 Set this to the location of your alias file.
247 If not set, no aliasing will be done.
249 Default: <not set> (i.e. no aliasing is done)
251 .TP
252 \fBcaseless_matching = \fIboolean\fR
254 If this is set, aliasing and the matching for \fBlocal_addresses\fP and
255 \fBnot_local_addresses\fP will be done caseless.
257 Note: Be sure to change this option only if the queue is empty as
258 correct processing of queued messages is not guaranteed otherwise.
260 Default: false
262 .TP
263 \fBpipe_fromline = \fIboolean\fR
265 If this is set, a from line will be prepended to the output stream whenever
266 a pipe command is called after an alias expansion.
267 Default is false.
269 .TP
270 \fBpipe_fromhack = \fIboolean\fR
272 If this is set, each line beginning with `From ' is replaced with `>From '
273 whenever a pipe command is called after an alias expansion.
274 You probably want this if you have set \fBpipe_fromline\fR above.
275 Default is false.
277 .TP
278 \fBmbox_default = \fIstring\fR
280 The default local delivery method.
281 Can be mbox or mda.
282 You can override this for each user by using the \fBmbox_users\fR or \fBmda_users\fR (see below).
284 Default: mbox.
286 .TP
287 \fBmbox_users = \fIlist\fR
289 A list of users which wish delivery to an mbox style mail folder.
291 .TP
292 \fBmda_users = \fIlist\fR
294 A list of users which wish local delivery to an mda.
295 You have to set \fBmda\fR (see below) as well.
297 .TP
298 \fBmda = \fIexpand string\fR
300 If you want local delivery to be transferred to an mda (Mail Delivery Agent),
301 set this to a command.
302 The argument will be expanded on delivery time,
303 you can use variables beginning with a dolloar sign `$', optionally enclosed in curly braces.
304 Variables you can use are:
306 uid - the unique message id.
307 This is not necessarily identical with the Message ID as given in the Message ID: header.
309 received_host - the host the mail was received from
311 ident - the ident, this is either the ident delivered by the ident protocol
312 or the user id of the sender if the message was received locally.
314 return_path_local - the local part of the return path (sender).
316 return_path_domain - the domain part of the return path (sender).
318 return_path - the complete return path (sender).
320 rcpt_local - the local part of the recipient.
322 rcpt_domain - the domain part of the recipient.
324 rcpt - the complete recipient address.
326 Example:
328 mda="/usr/bin/procmail \-Y \-d ${rcpt_local}"
330 For the mda, as for pipe commands, a few environment variables will be set as well.
331 See \fBmasqmail(8)\fR.
332 To use environment variables for the mda, the dollar sign `$' has to be escaped with a backslash,
333 otherwise they will be tried to be expanded with the internal variables.
335 .TP
336 \fBmda_fromline = \fIboolean\fR
338 If this is set, a from line will be prepended to the output stream whenever
339 a message is delivered to an mda.
340 Default is false.
342 .TP
343 \fBmda_fromhack = \fIboolean\fR
345 If this is set, each line beginning with `From ' is replaced with `>From '
346 whenever a message is delivered to an mda.
347 You probably want this if you have set \fBmda_fromline\fR above.
348 Default is false.
350 .TP
351 \fBonline_detect = \fIstring\fR
353 Defines the method masqmail uses to detect whether there is currently an online connection.
354 It can have the values \fIfile\fR or \fIpipe\fR.
356 When it is set to \fIfile\fR, masqmail first checks for the existence of \fBonline_file\fR
357 (see below) and if it exists, it reads it.
358 The content of the file should be the name of the current connection as defined
359 with \fBconnect_route.\fIname\fR (trailing whitespace is removed).
361 When it is set to \fIpipe\fR, masqmail calls the executable given by the
362 \fBonline_pipe\fR option (see below) and reads the current online status from its standard output.
364 No matter how masqmail detects the online status,
365 only messages that are accepted at online time will be delivered using the connection.
366 The spool still has to be emptied with masqmail \fB\-qo\fIconnection\fR.
368 .TP
369 \fBonline_file = \fIfile\fR
371 This is the name of the file checked for when masqmail determines whether it is online.
372 The file should only exist when there is currently a connection.
373 Create it in your ip-up script with e.g.
375 echo "connection-name" >/var/run/masqmail/masqmail-route
377 chmod 0644 /var/run/masqmail/masqmail-route
379 Do not forget to delete it in your ip-down script.
381 .TP
382 \fBonline_pipe = \fIfile\fR
384 This is the name of the executable which will be called to determine the online status.
385 This executable should just print the name of the current connection to
386 the standard output and return a zero status code.
387 masqmail assumes it is offline if the script returns with a non zero status.
388 Simple example:
390 #!/bin/sh
392 [ \-e /var/run/masqmail/masqmail-route ] || exit 1
394 cat /var/run/masqmail/masqmail-route
396 exit 0
398 Of course, instead of the example above you could as well use \fIfile\fR as
399 the online detection method, but you can do something more sophisticated.
401 \fIfile\fR must contain an absolute path to an executable program.
402 It can contain optional arguments.
404 Example: \fI/bin/echo foo\fR
405 (This tells masqmail to be always online with connection `foo'.)
407 For querying a masqdialer server
408 (= asking it whether a connection exists and what its name is)
409 use:
411 online_method=pipe
413 online_pipe="/usr/bin/mservdetect localhost 224"
416 .TP
417 \fBident_trusted_nets = \fIlist\fR
419 \fIlist\fR is a list of networks of the form a.b.c.d/e (e.g. 192.168.1.0/24),
420 from which the ident given by the ident protocol will be trusted,
421 so a user can delete his mail from the queue if the ident is identical to his login name.
423 .TP
424 \fBerrmsg_file = \fIfile\fR
426 Set this to a template which will be used to generate delivery failure reports.
427 Variable parts within the template begin with a dollar sign and are identical
428 to those which can be used as arguments for the mda command, see \fBmda\fR above.
429 Additional information can be included with @failed_rcpts, @msg_headers and @msg_body,
430 these must be at the beginning of a line and will be replaced with the list of the failed recipients,
431 the message headers and the message body of the failed message.
433 Default is /usr/share/masqmail/tpl/failmsg.tpl.
435 .TP
436 \fBwarnmsg_file = \fIfile\fR
438 Set this to a template which will be used to generate delivery warning reports.
439 It uses the same mechanisms for variables as \fBerrmsg_file\fR, see above.
441 Default is /usr/share/masqmail/tpl/warnmsg.tpl.
443 .TP
444 \fBwarn_intervals\fR = \fIlist\fR
446 Set this to a list of time intervals, at which delivery warnings
447 (starting with the receiving time of the message) shall be generated.
449 A warning will only be generated just after an attempt to deliver the mail
450 and if that attempt failed temporarily.
451 So a warning may be generated after a longer time, if there was no attempt before.
453 Default is "1h;4h;8h;1d;2d;3d"
455 .TP
456 \fBmax_defer_time\fR = \fItime\fR
458 This is the maximum time, in which a temporarily failed mail will be kept in the spool.
459 When this time is exceeded, it will be handled as a delivery failure,
460 and the message will be bounced.
462 The excedence of this time will only be noticed if the message was actually tried to be delivered.
463 If, for example, the message can only be delivered when online,
464 but you have not been online for that time, no bounce will be generated.
466 Default is 4d (4 days)
468 .TP
469 \fBlog_user = \fIname\fR
471 Replace \fIname\fR with a valid local or remote mail address.
473 If this option is set, then a copy of every mail,
474 that passes through the masqmail system will also be sent to the given mail address.
476 For example you can feed your mails into a program like hypermail
477 for archiving purpose by placing an appropriate pipe command in masqmail.alias
479 .TP
480 \fBmax_msg_size\fR = \fIbytes\fR
482 This option sets the maximum size in bytes masqmail will accept for delivery.
483 This value is advertised to the SMTP client by the `SIZE' message during SMTP
484 session setup.
485 Clients pretending to send, or actually send,
486 more than \fIbytes\fR will get a 552 error message.
488 `0' means no fixed maximum size limit is in force.
490 Default is 0 (= unlimited).
492 .TP
493 \fBdefer_all\fR = \fIboolean\fR
495 If set to true, masqmail replies with ``421 service temporarily unavailable''
496 to any SMTP request and shuts the connection down.
497 Note: This option is for debugging purposes only.
499 Default: false
