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?
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.
