That's just SIMS reading in queued messages at startup, so it does not say much about how your machine is being abused. If you have the logs for the arrival of that message, it might provide more clues.

The basic rules for keeping SIMS from being abused as a relay are:

1. Use the latest (last) version: 1.8b9d14
2. Make sure 'relay for clients only' is checked.
3. Watch for password-guessing attacks against POP3 or SMTP AUTH.

Without the records of how that mail arrived, it is impossible to know what exactly was done by the spammer.




Thanks a lot, thats what i did. looked at logs and saw a POP3 attack, had one of the accounts with a very easy username and password.


Spammer is blocked now.
