Hello,

While looking to building a email gateway to front my exchange I found first, Mailscanner then EFA. Very easy to build and setup. I am still playing with it and there seems to a lot that been built in over the years.

What is enabled by default, and what do you need to be tweaked for an effective filtering solution?

Tweaking is welcome. Check out the wiki and the forums for various tips.

A great place to see the default configurations is the various configs, such as

/etc/MailScanner/MailScanner.conf
/etc/postfix/main.cf
/var/www/html/mailscanner/conf.php
/etc/mail/spamassassin/*

Also, check the various options in EFA-Configure, which will handle many common settings for you.
