I recive spam from my domain

[lluis123]

Hello,

I recive spam from my domain using my account. If i do a telnet mail.mydomain.com 25 then if i enter a mail from: [email protected] and then in the rcpt to: [email protected] , then i recive this message without authentification, I don't have relay because rcpt to only accepts existing emails in my server, and the rcpthosts have only the domains in my server.

I read this issue with qmail but no solution :S, also i read about "joe job". I active SPF and i have less spam but i have spam using my server.


Any solution?

We use plesk 9 for windows.
we have the same problem. every day we received too many spam emails that has been send by our email address by our mail server.
Also we protect our mail server by "domain.key, Allow signing outgoing mail, ...", But Still Spammer sending emails by our mail server to our and server by our email address.
The spam protection service after upgrade to version 9 still dosen't work.
