This rig (Postfix 2.0.19 snapshot, RedHat RHEL3) does not have enough
RAM to run the proxy, unfortunately. Maybe I'll buy some more RAM next
month. In the mean time, I'm more interested in the pure Postfix
possibilities with the various pcre filters. *This is marvelous stuff*
and a Postfix special (header_checks, body_checks, etc) which Exim 4
simply doesn't have at this level. There are *more* things that keep me
latched onto Postfix :)

Maybe we're talking about different proxies. If I could use the smtp
amavisd-new/SA proxy, I wouldn't be doing all this. But it's interesting
and has taught me a great deal about Postfix.

Best,
