Hi!

I'm stuck in .forward hell. I'm in the process of migrating a "grown
system" to postfix. So far, so good. Everything works as it should,
expect for some minor things:

I get a lot of mailer loops due to strange .forward files (which
worked with sendwhale -- of course), let me give you one example:

Mail to: oberende
"keywest.fmi.uni-passau.de" gets appended (FQDN of the host I'm sitting
on). This host has a sendmail nullclient setup, everything goes to
smarthost running postfix.

Smarthost vivaldi.fmi.uni-passau.de rewrites using a canonical map:

/(.*)(.*)\.fmi\.uni-passau\.de/ $1infosun.fmi.uni-passau.de
/(.*)(.*)\.infosun\.fmi\.uni-passau\.de/ $1infosun.fmi.uni-passau.de

oberendekeywest.fmi.uni-passau.de to
oberendeinfosun.fmi.uni-passau.de

which is recognised as local by vivaldi.
Local delivery occurs. ".forward" contains
"oberendelrs.fmi.uni-passau.de"

So the mail gets forwarded there.

The address gets rewritten once more using canonical to
oberendeinfosun.fmi.uni-passau.de
and there we have the mailloop.

a) Is there any way to say "forward the mail there, regardless of
   rewriting"?
b) Is there a way to exempt a certain destination from being rewritten
   using canonical maps?
   E.g. mail.fmi.uni-passau.de stays untouched

Ah, young webmaster... java leads to shockwave. Shockwave leads to
realaudio. And realaudio leads to suffering.
