If you do want to delete mail tagged as spam, you really need to consider where you put the borderline. By default, SpamAssassin will call all messages scoring over 5.0 spam. If you set the "delete" threshold at 5.0, there's a real risk that you'll delete legitimate mail that happened to score slightly over 5.0. You should consider setting a deletion threshold at something considerably higher than 5.0 – maybe as high as 10 or 15 points.

It's not too difficult to write a non-spam message that scores 6.0. But it's quite hard to accidentally write a message that scores over 15! On the other hand, spammers seem quite capable of writing messages that score 30 or more points.

You really do need to make sure your users are aware of any policy that will result in messages being deleted without them knowing about them. You might possibly need to be sure that doing this is permissible under the laws that apply in your jurisdiction.

If you're working in an organisation that might get upset if legitimate messages "go missing", you might need to get an auto-delete policy signed off by management, just to ensure you are covered when the mail that clinches a multi-million deal gets auto-deleted because it scored 5.1 when the auto-delete threshold was set at 5.0.

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