Hi. I have little knowledge on Linux POP3 servers and I want to do this. I want to check the email as it arrives on the server and check message source and delete it according to a set of regexp rules. I am not a host, I just have a shell account.

As a user I think Procmail will work for you. If you use exim, then I think it comes with it's own filter which a user can modify. Ask the host for more information.

Okay, procmail..I'll take a look. Contacted support now. They don't use exim.

Damn...more than 800 e-mails in 20 minutes. :(

Okay, I just discovered my host supports IMAP (The account specs didn't say). I'm gonna play with procmail now...hehe now taking care of spiced ham.

Thanks for the info on that one Shyne.
