NAME

masqmail.route - masqmail route configuration file

DESCRIPTION

This man page describes the syntax of the route configuration files of masqmail (8). Their usual locations are in /etc/masqmail/. Mail will be sent with the SMTP protocol to its destination, unless `pipe' is given. In this case the message will be piped to the given program.

ROUTE CONDITIONS

allowed_senders = list This is a semicolon `;' separated list of envelope sender addresses. Messages which have one of these addresses as the return path (= mail from) are allowed to use this route (if not also in denied_senders). Glob patterns containing `?' and `*' can be used. The special item "<>" matches the null sender address (eg. failure notices or delivery notifications). If the pattern doesn't contain an `@', it is seen as a pattern for the local part only. Example: meillo;*@*example.org;web*@example.com (``meillo'' equals ``meillo@*'', i.e. the local part.) denied_senders = list This is a semicolon `;' separated list of envelope sender addresses. Messages which have one of these addresses as the return path (= mail from) will not be sent using this route (even if also in allowed_senders). Glob patterns containing `?' and `*' can be used. The special item "<>" matches the null sender address (eg. failure notices or delivery notifications). If the pattern doesn't contain an `@', it is seen as a pattern for the local part only. Example: (see allowed_senders) allowed_recipients = list A list of envelope recipient addresses where mail can be sent to using this route. This is for example useful if you use this route configuration when connected to another LAN via ppp. Glob patterns containing `?' and `*' can be used. Example: *@example.org;*@*foo.bar (See also examples for allowed_senders) denied_recipients = list A list of envelope recipient addresses where mail will not be sent to using this route. This is for example useful if you send mail directly (mail_host is not set) and you know of hosts that will not accept mail from you because they use a dialup list (eg. http://maps.vix.com/dul/). denied_recipients overrules allowed_recipi‐ ents. Glob patterns containing `?' and `*' can be used. Example: *@spamblocker.example.org (See also examples for allowed_senders) last_route = boolean If this is set, a mail which would have been delivered using this route, but has failed temporarily, will not be tried to be delivered using the next route. If you have set up a special route with filters using the lists `allowed_recipi‐ ents' and `allowed_senders' or their complements (denied_), and the mail passing these rules should be delivered using this route only, you should set this to `true'. Otherwise the mail would be passed to the next route (if any), unless that route has rules which prevent that. Default is false. connect_error_fail = boolean If this is set, a connection error (or if a pipe command could not be executed) will cause a mail delivery to fail, ie. it will be bounced. If it is unset, it will just be defered. Default is false. The reason for this is that masqmail is designed for non perma‐ nent internet connections, where such errors may occur quite often, and a bounce would be annoying. You probably want to set this to true for permanent routes.

SMTP CONFIGURATION

mail_host = string This is preferably the mail server of your ISP. All outgoing messages will be sent to this host which will distribute them to their destinations. If you do not set this mails will be sent directly. Because the mail server is probably `near' to you, mail transfer will be much faster if you use it. You can optionally give a port number following the host name and a colon, eg mail_host="mail.foo.com:25". resolve_list = list Specify the method how the domain of the server is resolved. Possible values are dns_mx, dns_a, byname. For `dns_mx', the domain is assumed to be an MX pointer to a list of host names, these will be tried each in order (lowest preference value first, equal preference values in random order). For `dns_a', the domain is assumed to be an A pointer. For `byname', the library function gethostbyname(3) will be used. For routes to a local network, where you likely don't have a DNS service, use only `byname'. The default is "dns_mx;dns_a;byname". helo_name = string Set the name given with the HELO/EHLO command. If this is not set, host_name from masqmail.conf will be used, if the do_correct_helo option (see below) is unset. do_correct_helo = boolean If this is set, masqmail tries to look up your host name as it appears on the internet and sends this in the HELO/EHLO command. Some servers are so picky that they want this. Which is really crazy. It just does not make any sense to lie about ones own identity, because it can always be looked up by the server. Nobody should believe in the name given by HELO/EHLO anyway. If this is not set, host_name from masqmail.conf or as given with the helo_name (see above) will be used. instant_helo = boolean If this is set, masqmail does not wait for the greeting of the SMTP server after opening the connection. Instead it says EHLO right away (ESMTP is assumed). Use this option with wrappers that eat the 220 greeting of the SMTP server. Common examples are STARTTLS wrappers, like `openssl s_client -starttls smtp ...'. If this option is set and a 220 greeting is received though, everything should still work. Please don't rely on that and keep in mind that RFC 2821 says that the client SHOULD wait for the 220 greeting of the server. Default: false do_pipelining = boolean If this is set to false, masqmail will not use ESMTP PIPELINING, even if the server announces that it is able to cope with it. Default is true. You do not want to set this to false unless the mail setup on the remote server side is really broken. Keywords: wingate. auth_name = string Set the authentication type for ESMTP AUTH authentication. Currently only `cram- md5' and `login' are supported. auth_login = string Your account name for ESMTP AUTH authentication. auth_secret = string Your secret for ESMTP AUTH authentication. wrapper = command If set, instead of opening a connection to a remote server, command will be called and all traffic will be piped to its stdin and from its stdout. Purpose is to tun‐ nel ip traffic, eg. for ssl. Example for SMTP over SSL tunneling: wrapper="/usr/bin/openssl s_client -quiet -connect mail.gmx.net:465 2>/dev/null" SMTP over SSL is supported since masqmail-0.1.8. It is marked obsolete by the IETF but is still in use. Example for encryption with STARTTLS (RFC-3207): # don't forget the instant_helo, otherwise it won't work instant_helo=true wrapper="/usr/bin/openssl s_client -quiet -starttls smtp -connect mail.gmx.net:25 2>/d ↲ ev/null" This is supported since masqmail-0.2.28. STARTTLS supersedes SMTP over SSL. Note for openssl: Ensure that stderr is redirected. Do *not* use -crlf in the wrapper command, because masqmail does already insert CRLF. However, you might want to specify -crlf if you want to test your wrapper command interactively on the command line.

PIPE CONFIGURATION

pipe = command command will be called and the message will be piped to its stdin. Purpose is to use gateways to uucp, fax, sms or whatever else. You can use variables to give as arguments to the command, these are the same as for the mda in the main configuration, see masqmail.conf(5). pipe_fromline = boolean Only if `pipe' is used. A from line will be prepended to the output stream when‐ ever a pipe command is called. Default is false. pipe_fromhack = boolean Only if `pipe' is used. Each line beginning with `From ' is replaced with `>From ' whenever a pipe command is called. You probably want this if you have set pipe_fromline above. Default is false.

ADDRESS REWRITE RULES

set_h_from_domain = string Replace the domain part in `From:' headers with this value. This may be useful if you use a private, outside unknown address on your local LAN and want this to be replaced by the domain of the address of your email address on the internet. Note that this is different to set_return_path_domain, see below. set_h_reply_to_domain = string Same as set_h_from_domain, but for the `Reply-To' header. set_return_path_domain = string Sets the domain part of the envelope from address. Some hosts check whether this is the same as the net the connection is coming from. If not, they reject the mail because they suspect spamming. It should be a valid address, because some mail servers also check that. You can also use this to set it to your usual address on the internet and put a local address only known on your LAN in the configuration of your mailer. Only the domain part will be changed, the local part remains unchanged. Use map_return_path_addresses for rewriting local parts. map_h_from_addresses = list This is similar to set_h_from_domain, but more flexible. Set this to a list which maps local parts to a full RFC 822 compliant email address, the local parts (the keys) are separated from the addresses (the values) by colons (`:'). Example: map_h_from_addresses = "john: John Smith <@mail.academic.edu>; charlie: Charlie ↲ Miller <@mx.commercial.com>" You can use patterns, eg. * as keys. map_h_reply_to_addresses = list Same as map_h_from_addresses, but for the `Reply-To:' header. map_h_mail_followup_to_addresses = list Same as map_h_from_addresses, but for the `Mail-Followup-To:' header. Useful when replying to mailing lists. map_return_path_addresses = list This is similar to set_return_path_domain, but more flexible. Set this to a list which maps local parts to a full RFC 821 compliant email address, the local parts (the keys) are separated from the addresses (the values) by colons (`:'). Note that this option takes RFC 821 addresses while map_h_from_addresses takes RFC 822 addresses. The most important difference is that RFC 821 addresses have no full name. Example: map_return_path_addresses = "john: <@mail.academic.edu>; charlie: <cmiller@mx.co ↲ mmercial.com>" You can use patterns, eg. * as keys. expand_h_sender_address = boolean This sets the domain of the sender address as given by the Sender: header to the same address as in the envelope return path address (which can be set by either set_return_path_domain or map_return_path_addresses). This is for mail clients (eg. Microsoft Outlook) which use this address as the sender address. Though they should use the From: address, see RFC 821. If fetchmail(1) encounters an unquali‐ fied Sender: address, it will be expanded to the domain of the pop server, which is almost never correct. Default is true. expand_h_sender_domain = boolean Like expand_h_sender_address, but sets the domain only. Deprecated, will be removed in a later version.
