For this you don't need to use filters.in.tab. You can use custom domain
processing:
CUSTOM DOMAIN MAIL PROCESSING
If a message that has as target domain of '*sub1.sub2.domain.net*'
arrives at the XMail server, '*AND*' XMail does not have a real domain
'*sub1.sub2.domain.net*' inside its domain list, XMail decides if this
domain gets a custom domain processing by trying to lookup:
sub1.sub2.domain.net.tab
.sub2.domain.net.tab
.domain.net.tab
.net.tab
.tab
inside the '*custdomains*' directory.
If one of these files is found the incoming mail gets custom domain
processing by executing commands that are stored in such a file.
The format is:
"command"[TAB]"arg-or-macro"[TAB]...[NEWLINE]
These tables store commands (internals or externals) that have to be
executed on the message file. The presence of one of these files is
optional and if none exist the default processing is applied to the
message via SMTP.
Each argument can be a macro also:
*@@FROM*
the sender of the message
*@@RCPT*
the target of the message
*@@FILE*
the message file path (the external command '*must only read*' the
file)
*@@MSGID*
the (XMail unique) message id
*@@MSGREF*
the reference SMTP message id
*@@TMPFILE*
creates a copy of the message file to a temporary one. It can be
used with 'external' command but in this case it's external
program's responsibility to delete the temporary file.
Supported commands:
*[EXTERNAL]*
"external"[TAB]"priority"[TAB]"wait-timeout"[TAB]"command-path"[TAB]=>
"arg-or-macro"[TAB]...[NEWLINE]
where:
*external*
command keyword
*priority*
process priority: 0 = normal -1 = below normal +1 = above normal
*wait-timeout*
wait timeout for process execution in seconds: 0 = nowait
Be carefull if using @@FILE to give the external command enough
timeout to complete, otherwise the file will be removed by XMail
while the command is processing. This is because such file is a
temporary one that is deleted when XMail exits from file processing.
*[REDIRECT]*
"redirect"[TAB]"domain-or-emailaddress"[TAB]...[NEWLINE]
Redirect message to internal or external domain or email address. If
the message was for [EMAIL PROTECTED] and the file
custdomain.net.tab contains a line:
"redirect" "target-domain.org"
the message is delivered to '[EMAIL PROTECTED]'.
While the line:
"redirect" "[EMAIL PROTECTED]"
redirects the message to [EMAIL PROTECTED]
*[LREDIRECT]*
"lredirect"[TAB]"domain-or-emailaddress"[TAB]...[NEWLINE]
Redirect the message to internal or external domain (or email
address) impersonating local domain during messages delivery. If the
message was for [EMAIL PROTECTED] and the file
custdomain.net.tab contains a line:
"redirect" "target-domain.org"
the message is delivered to '[EMAIL PROTECTED]'.
While the line:
"redirect" "[EMAIL PROTECTED]"
redirects the message to '[EMAIL PROTECTED]'. The difference
between ``redirect'' and ``lredirect'' is the following. Suppose [EMAIL PROTECTED]
sends a message to [EMAIL PROTECTED], that has a redirect to [EMAIL PROTECTED] With
``redirect'' [EMAIL PROTECTED] will see [EMAIL PROTECTED] has sender while with
``lredirect'' he
will see [EMAIL PROTECTED]
*[SMTPRELAY]*
"smtprelay"[TAB]"server[:port],server[:port],..."[NEWLINE]
Send mail to the specified SMTP server list by trying the first, if
that fails, the second and so on.
Otherwise you can use this syntax:
"smtprelay"[TAB]"#server[:port],server[:port],..."[NEWLINE]
To have XMail random-select the order the specified relays.
*[SMTP]*
"smtp"[NEWLINE]
Do SMTP delivery.
-
To unsubscribe from this list: send the line "unsubscribe xmail" in
the body of a message to [EMAIL PROTECTED]
For general help: send the line "help" in the body of a message to
[EMAIL PROTECTED]
