Is it sensible to simply delete all mail that SpamAssassin marks as being spam?

In general, no. While SpamAssassin is very good at picking out a large proportion of spam, it's impossible for a computer to do this job perfectly. You should only delete mail if you (and your users/customers) would find it acceptable to lose mail that might be legitimate. A much better idea is to filter possible spam into a separate folder that can be checked less frequently than the normal mailbox.

But I really really want to do it anyway!

tells how to configure procmail + SpamAssassin to delete email that looks like spam.

(EditHint: should we merge these 2 wiki pages, reducing one to merely a pointer to the other ?)

How can I configure procmail to bounce messages flagged as spam?

Don't bounce to the From-addresses. They're almost always forged. If you're own address has been abused by spammers as From-address you know what I'm talking about.

Yes, who can help with this

We use Exim 4.24 with DirectAdmin here in The Netherlands. Regards, Lee
