Anonymous access of my sendmail service
I have freeBSD Unix 5.4
I am facing a terrible problem with my sendmail.I have servers having live IPs.And I have sendmail running in my system.
Somebody is sending mail by using my sendmail service.I have checked the IPs and the domains but they are all randoms.In sendmail open relay is closed.I need the sendmail service for my own purpose . But before that I want to stop this random anonymous access of my sendmail service .Could u plzz tell me what to do.
It's very urgent
