I have a CentOS server with postfix running. A pop user's account was compromised and a lot of spam started being sent. My upstream ISP's mail program started refusing to talk to me because of the very high rate of mail, error 451. I disabled the compromised account. I then changed the postfix settings to deliver mail directly and flushed the mail queue. This resulted in spam being sent out.
There were about 20K mails in the queue. I don't know how I might have handled this better, I would have preferred to not send the spam, but the volume was large and the labour of sorting out spam from legit email was prohibitive.
Advice? A better list for this issue perhaps?

The postfix-users list seems perfect. http://www.postfix.org has more information.

man postsuper gives solutions to deleting the queued spam rather than dumping the problem onto the rest of the Internet.
Why didn't you ask for advice _before_ spewing another 20K spam onto the rest of us?

well basically it was late at night and I was very tired, not the best decision making time. I accept the criticism and will follow up as you suggest.
Not by any means 20k spams. I manually deleted about 2K mails and many of the rest were normal list traffic.
