Hi,

Can't help much with the sendmail specifics, but what I do whenever
someone is spamming me who I'm having trouble filtering with sendmail
rules is to filter all traffic from their ip (or range of IPs) to my port
25. No more mail relaying. Hope this helps you. I use ipfw.

> Im under spam attack, and implemented the "Refuse Mail From Selected
> Relays" from sendmail.org. It doesnt block relaying at all, but blocks
> access from sites stored in /etc/mail/DeniedNames
