Hello,

I am trying to run two postfix instances and amavisd on one host.
The second postfix instance is needed because I want to pass some
mail through amavisd, whereas some mail, relayed elsewhere
(to host whirlwind.atmosp.physics.utoronto.ca), should not
be scanned. The problem is that I cannot make it work. I read that
each instance should be running on a separate hostname or IP. I
tried both, no difference: bounce with "loops back to myself".

Here are excerpts from configs for the case of 2 separate IPs,
  128.100.80.90 for haboob.atmosp.physics.utoronto.ca,
  128.100.80.98 for webmail.atmosp.physics.utoronto.ca.

What is wrong here? Your advice is greatly appreciated.

Alex
