Some of my users are receiving spam which says its coming from their own mailing address. It is typically related to shopping or something like that. Is there a way to block a user from receiving mail from his/her address?

Mark them as spam and use blocklists. It's a better long term solution than blocking on a From-address.

We use, and as blocklists.

I had the same problem. I've removed the default auto anti spam rule and created a subject based rule. That way All messages with ***SPAM*** in te subject are placed into the junkmail folder.

You can also setup spf/callerid as discussed in this forum, thread title: "How to deal - Spam sent by a local user"
