I wasn't sure if this should be in the 'software' or 'networking' thread, but oh well. I'm trying to set up procmail to send all messages from machine 'A' to machine 'B' for spam filtering, then send it back to machine 'A' for delivery into the users' mail directories. Although it may seem like an odd thing to do, believe me, it will be much less work then the other situations. Machine 'A' is performing too many tasks as it is, and I think installing spamassassin and clamav will be too much for it, considering all the emails it receives. There are WAY too many users to just have the mail delivered to machine 'B' and have them check it from there. It would take forever to make all the user accounts. So the mail must be returned to machine 'A' after filtering. How can I set this up. preferably in procmail, since it is already in use on both machines?

I just went through a lot of reading on this.

I wanted to do something similar. Your request is a few months old. If you still need help reply to this and I'll try to point you in the right direction.

yes, I still need a lot of help with this. Any advice would be much appreciated.
