  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Spam issues from own E-Mail internal

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!
