• 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.

SMTP Error only with SOME MAil Clients but not with Outlook

Maybe someone could help me with this crazy authentification problem:

With outlook and smtp authentification is sending via SMTP possible.

With programs, like tobit david or mozilla thunderbird the server stops login with an authentification error like: This Server needs Auth...

But this is activated!

The POP3 Access (with same password) is problem free.

I can't find the problem - why does outlook work with smtp and the other mail clients not?

In Plesk nothing is black listed and authentification is enabled.

Please could anyone help me to locate the error?

EDIT: Oh, this post should have been in plesk 7 for win area, maybe someone could move it....thx!
