I am currently running sendmail and spam assassin version 2.x. I am upgrading my mailserver and installing postfix. I have a few questions regarding "what is best"
First, should I store my users (about 150) in the passwd file or in an mysql database ?
I have no postfix experience, so I can't speak to that part.
From a SA perspective, if your SA box is a forwarding relay it is kind of nice to not have to create login accounts for all your users but still allows them to have their own user_prefs..
Does spamassassin v3 require a mysql database to work ?
No.
Is it recommended ?
It's a very handy way for multiple MXes to share a bayesdb and user prefs. It also allows you to stick your database on a separate box, lightening the CPU load of your MX a bit.
And, from what I've heard, it's faster. However, I'm not sure if the person reporting improvement used mysql on the same box, or set up a separate database server.
Do I need it to use bays ?
No. SA version 3 can still use DB_File type databases.
