Someone is trying to post spam to mailing lists on my server. They are sending spam to the correct mailing list address with my old email address in the From: field.

Since I'm subscribed to the list with my new address, the Minimalist mailing list manager bounces spam back to me, with the attached warning saying that I'm not subscribed.

I got 50 such emails in just one day. This would wrack havoc on the mailing list if they would succeed to spoof my proper email address.

Is this only a coincidence or is this work of some bot that is smart enough to find the email addresses of people that are subscribed to the list (from the list's archives for example) and spoof them?

I don't currently see any simple way of preventing people from providing spoofed email addresses to the Minimalist. This spam is coming from a DSL IP range in Morocco so if this will get any worse, I'll simply route this IP range to /dev/null.
