external smtp Plesk 'the server sent an empty reply'

Question

Situation:

I got a Domain hosted on "strato.de" and i got a Linux Server hosted by "hetzner.de".

Domain configuration:

A Record -> Linux Server IP
MX Record -> Use Strato Intern Mailserver

Server configuration:

Hostname -> Domainname from Strato

I used "external SMTP Server in Plesk"

Host: smtp.strato.de
Post: 465
Username: **Username**
Password: **Password**

my /var/log/mail says

Jun 10 07:59:34 **DOMAIN** msmtp: host=smtp.strato.de tls=on auth=on user=info@**DOMAIN** from=**DOMAIN**@**DOMAIN**.de recipients=**[email protected]** errormsg='the server sent an empty reply' exitcode=EX_PROTOCOL

I already installed a fresh Plesk/Linux and I also tried to set the MX record to the Server and tried to use SMTP Server on the Linux. That didn't work either.

GOAL:

I want the domain from Strato to point to the Hetzner Linux Server (done A-Record).

I want the emails that the server generates to be sent; I already had this one working but the server sent emails with IP not with the pre-bind Domain. that's bad for GMX because they refuse mails from IP Sources.

Can someone give me advice ?

(Posted answer on behalf of the OP):

I used this guide and installed Postfix manual from SSH console. It is working as it should. I had to Bind the smtp to pot 587 instead of 456 because 456 is only for public signed certificates not for self-signed.
