Spam issues from own E-Mail internal

[Mario1989]

Hello,

I've got a question about the Postfix Mail Server. (Using in Plesk 11.5.30 Update 33 / Debian 6.0.9)

The Option: Tools -> Mailserver-configuration -> Relaying options is set to "authorization needed" + SMTP. So the Server got no open Relay.

Now i recieved a lot of spam from my own E-mail Adress.

By using "Wormly SMTP testing tool" is it possible to send an Email (only from the registered Email adresses) to another internal Email (also registered at my Domain). Without knowing any password.

Is it possible to activate an SMTP authorization (or something else) for sending internal Emails ?

Thanks a lot.

Not as far as I'm aware. If the server did not accept email for your own hosted domains without authentication, no external email could be delivered to any of those domains.

But as I don't (yet) use Postfix, maybe there's some trick to it!
