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@example.com and then in the rcpt to: firstname.lastname@example.org , 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?
