Every now and then I find thousands of spam messages in mail queue! These messages are sent from some foreign IPs and are being accepted by server to forward them to hotmail, yahoo, gmail, etc. addresses!!
How come my server accepts these messages and send them on behalf of spammers
Do I have very insecure server?! What can I do to stop my server acting foolishly?!
Your server likely had a php script exploited and now its being used to send spam.
