Sendmail: Store and Forward Configuration
 

I have looked all over the place and have had no luck finding any type of guide on how to set up Sendmail in a store and forward configuration. Can someone point me in the right direction?

Conversely, if Sendmail is not the best tool I would also be open to suggestions.

Requirements:
RBL lookups
Spam Assassin compatible
install/updates from a repository strongly preferred

Thanks for the help

Platform: CentOS 5.x

Check out MailScanner (www.mailscanner.info). It's great with RBLs and SpamAssassin, and store and forward is cake. A very powerful product with a very helpful group on the mailing list and a pretty good Wiki.

We have a few servers using Sendmail with MailScanner.
