General SA questions, somewhat OS X specific

[Scott Haneda <li...@newgeo.com>]

I run a legacy mail server that does not support SpamAssasin yet.  I would
like to run my mail through SpamAssassin now though, and was thinking I
could change my MX to point to a proxy that has SA installed and then
forwards off to my legacy email server.

I assume this is possible.

I have been told SA can run as a standalone MTA, if that is the case, this
is good news.  If not, can someone point me to links that would help me with
this install.  I just barely know postfix, and this is all going to happen
on OS X 10.3 client, so hopefully someone who has been through this can help
and point me to some links that will get me going.

Thanks

Well, SA can't run AS a standalone MTA, ie you still need a MTA program
like postfix, exim, etc.  However, SA can be integrated at the MTA
layer, and be called as mail is processed by the MTA.

Pretty much what you want to do is set up a stand alone MTA, such as
postfix, and have that MTA be configured to either be your mailserver,
or forward to your existing MTA. (The forwarding case creates a
proxy-esque scenario, and the alternative is to just replace the
existing mailserver entirely).

Once you've got that set up, you can integrate SA into the MTA so it
gets called as mail is received.
