I need to come up with a decent POP server that is relatively painless 
to implement (if one exists) on a Yellow Dog 3.0 install.

Please keep in mind that you're responding to someone who hasn't done it 
before for the most part.   :-)

I would like to use a combo of Postfix and the POP, along with Procmail 
to do some more serious low-level filtering of mail that comes in.

Can some of you comment on how you have your mail servers setup and what 
methods you use to strip attachments?

I have worked a little before on .procmailrc (I think that was the name 
of the file), but it's been awhile.

Thanks!

Chris
