Well, you don't have to try very hard to start a holy war around here
;-) Seriously, though, I wasn't thinking at the level of amavisd,
mimedefang, or mailscanner.
Those may come later, but the situation I'm in right this moment is
that I'm taking over a very idiosyncratic mail environment, and I need
to tune and monitor it's performance before switching over. Thus, the
least disruptive option I see is to insert a milter for spamassassin
in front of anything else, and then score / log messages without
tampering with them in anyway, so they can continue through the milter
chain as if it weren't even there (except for some slight delay).
Spamass-milter does this, but it means running the milter on the
existing system rather than just pointing sendmail to a remote
milter. I may end up there anyhow, but I thought I'd ask first.
All this, of course, after searching high and low for a milter, proxy,
or some other contraption that would allow me to "clone" a mail stream
to a totally separate server without disrupting the original stream
(like port spanning or a network tap, but for SMTP), and finding
nothing outside of alpha or beta to do that. If anyone knows of
something like that, I'd be interested to hear about it as well.
As this doesn't feel like your personaly mail server, I would advise you
against cloning production traffic in transit. If something goes wrong
in the clone... yuk.
