Any one of your mail account might be compromised. The server is using port 587 to accept mails from local users? . /var/log/qmail/submission or /var/log/qmail/smtp will tell the truth. say for example, search for "[email protected]" in above mentioned logs. So that we can get the origination of this mail. If it is using a local mail id for authentication, reset the password of the mail. Also remove the mails in queue using qmail-remove. --Senthilvel.
