Hi,
I would like to configure a bizarre setup like this:
if the mail is sent as usual, do not use a smart-host, just
deliver (that is easy and works)
if the recipient domain ends in ".through-smart-host", it should
deliver via a SMTP relay (smart-host). Of course, just before
delivering, it should remove the ".through-smart-host" suffix.
Something like this could be interesting:
s/^(.+)\.through-smart-host$/$1/ smtp:[smart-host]
However I didn't figure out how to implement this using pcre_table(1).
If all fails, I could create a new UNIX mailer in master.cf and route
through it, and make it deliver the mail (e.g. through a nullmailer
or something) after changing the destination with a Perl script,
but that would be complicated, slow and clumsy.
Does anyone have any suggestion ? (basically, what I want is the
obsolete mixed UUCP/domain routing, such as [EMAIL PROTECTED],
but that doesn't usually work anymore nowadays)
Yes, you should be able to do this with a transport_maps entry
and a regexp (or pcre) smtp_generic_maps.
# main.cf
transport_maps = hash:/etc/postfix/transport
smtp_generic_maps = regexp:/etc/postfix/generic.regexp
# transport
through-smart-host smtp:[smart-host]
.through-smart-host smtp:[smart.host]
# generic.regexp
/^(.*)\.through-smart-host$/ $1
