Resolved smtp hostname problem, urgent

[JogoVogo]

Server operating system version

CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

Plesk Obsidian v18.0.48_build1800221104.03 os_CentOS 7

Hello together!

After a migration to a new plesk server it is no longer possible to use the same hostname on the outgoing SMTP server as on the incoming server (imap/pop).

if you enter the hostname of the machine itself as smtp server instead, it works.

imap and pop works under the hostname. SMTP (postix), not.
If you enter the hostname of the machine as SMTP server it works.

The problem is that there are about 400 mailboxes now which have the name [email protected] entered as the outgoing mail server.

Before migration it works fine. imap/pop as well as smtp had the same hostname.

An idea, urgent...

Could you please explain this in detail? How do you change the Hostname? and what is the expect result etc?

Hi, the hostname is the same as before. Only the IP has changed.

DNS entries have been made accordingly.

The problem is that an imap and POP works, but SMTP does not.

The hostname is the plesk machine itself is e.g. , "x123.foo.de".

imap smtp "mail.foo.de"

imap works, smtp not under "mail.foo.de", under "x123.foo.de" smtp works.

What did you mean by,

imap works, smtp not under "mail.foo.de", under "x123.foo.de" smtp works.

Did you check the "Tools & Settings" > "Mail Server Settings"?

 

[JogoVogo]

It is not possible to send via "mail.foo.de".
