Quoting Mark Jeftovic (markjr(_at_)easydns(_dot_)com):
I was wondering what happened to the list, until I figured out today
that one of my procmail receipes was misfiling all the posts.
So this may be a clueless question at this juncture: has there been
a successful SRS implementation under postfix 2.x ?
I implemented SRS in Postfix with Mail::SRS, a policy daemon, and
a patch to Postfix that implements a REWRITE action. The guts of
the policy daemon:
if ($attr{"sender"} ne '')
{
return ("SENDER_REWRITE " . $SRS->forward($attr{"sender"},
'srs-forwarder.mumble.net'));
}
return "DUNNO";
The REWRITE action patch came from here:
http://rmxf.comm.pl/
The rewrite is the result of a Postfix restriction and it must be
done after final destination is determined. In my case I do the
rewrite in a Postfix instance running on my outbound customer SMTP
servers and use transport maps on the MX servers to direct forwarded
mail to the rewriter.
I don't forward much mail so a perl implementation works OK for me.
For volume a SRS implementation in C with a tcp_table map daemon
would be more efficient.
Its messy but it works. I do believe a native Postfix implementation
will be even more messy.
