What MTA do you run?
seifried.org Mail looks like this:
Sorry when I asked what MTA, I wanted to know what MTA Alex runs.
Alex, please tell us what MTA you run!
Your mail structure looks nice!

Firewall - OpenBSD with spamd (defaults) and very agressive
greytrapping.This catches about 90% of my spam (the main idea is to
reduce load on spamassassin and make sure I'm talking to a real mail
server). For example if you try to email kurs@seifried.org or
kuru@seifried.org you get black listed (so often spammers go in
alphabetical order hit those before kurt@seifried.org) I also have a
script that checks the maillogs for undeliverable addresses and adds
those (about 3000 in all added, very few new ones being added now).

Incoming MX servers - two servers running Postfix with various anti-spam
things enabled.
|
Mail server - Postfix server with spamassassin and some procmail
filtering for attachments/etc to my personal accounts. IMAPS server for
mail retrieval.
So tell me once your OpenBSD accepts the mail, it goes to the postfix
machines. Does the OpenBSD server know what users are valid and what
aren't? Do you postfix MXs know what users exist or don't?
So currently I have two main lines of defense against spam: OpenBSD
spamd and spamassassin. I have not yet enabled Bayes filtering, which
would provide an additional level of spam filtering (I get 2-3 spams a
day to my accounts so it's not enough to bother me enough to setup Bayes
filtering).
I am running SA on my server, it work well but I am studying a move onto
dspam. I think it will give me much more granularity than SA, people say
that it is also much more accurate. I am yet to see!
