sendmail miltering is nice and shouldn't be all that hard to
troubleshoot. It's a little confusing getting it set up (making sure
that the sockets are all pointed to the same file)

I tend to not trust walk-through type stuff because it is always done
from a specific point of view and once you start to wander, things break
and you don't know why.

I don't know anything about ISPConfig but I suspect that the reason is
that it isn't all that popular.

Consider, virtualmin...(though it appears that virtualmin supports
CentOS so you may have to lie and tell it you're running CentOS 5.0)

it's not really a's just his cycle for things and the 4.66
which he still classifies as Beta has fixes for the recent
perl-Mail-Tools (or was it perl-Mime-Tools?) which would break what he
classifies as 'stable'

The last time I played with amavisd-new, I hated it so I stay with
MailScanner...there is ample info on setup on their web site, including
integration with Postfix (or Sendmail)
