I just had a spammer take over an account which is allowed to send mail via one of my servers. I ran the lock account script but it kept on going. It seems that if a SASL authenticated user doesn't close the session then Postfix doesn't notice that the account is no longer valid and keeps allowing mail through! How can I solve this? Apart from restarting Postfix whenever I lock an account. Is there some way of limiting how many messages a smtpd process will accept before it exits? I'd like to force it to exit after processing 10 or 20 messages so that SASL authentication has to be completed again for the next 10 or 20 messages. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
