How do I configure sendmail to block all OUTGOING mail FROM one userid TO the world?
Hello,
ENVIRONMENT:
OS: Solaris 10
Sendmail: 8.13.8+Sun
BACKGROUND:
We had a user account that was compromised and was used as a relay. She sent out (or would have if we didn't kill sendmail) ~10K emails alerting people they just won $75K.
The target for this spam was everyone internal to our company and EVERYONE with an @aol.com address, maybe other domains as well, we just stopped looking. Stopping all mail for our company until we took her offline was not a suitable solution.
QUESTION:
Is it possible to configure sendmail as to block ALL OUTGOING email from ONE user? I don't want to shut down mail for the entire organization again. I've seen solutions on how to block INCOMING and how to block outgoing TO targets, but not how to block ALL OUTGOING FROM the sender.
Any help would be greatly appreciated.

I need to set up sendmail so that it can send mail to a mail relay.
I have never touched sendmail before so I am not sure how to do this. All incoming mail is directed to a different server - this is just to enable me to get mail out.
