Issue E-Mail problem

[marco2306]

Hello Community,
I recently got a VServer with Plesk (Plesk ® Web PRO Edition).
I created everything according to my needs, including e-mail inboxes.
I can write e-mails, but they are not sent and are placed in the queue.
How can I fix the problem?

Sorry for my bad english, is translated by google translate.



Debian 9.13‬
Produkt: Plesk Obsidian 18.0.29 Update Nr. 1




With kind regards

Hi,
please check logfiles under /var/log/syslog and the maillogs in /var/log.
Further check if postfix service is running.

Greetings

I have an excerpt from maillog and syslog in the text file.
Of course, I tried to write an email beforehand.
This is only a small extract from both, as both logs are huge.

With kind regards

It seems your server is blocked by telekom mail servers.
Can you check with other servers?
For troubleshooting test connection with telnet.

 

[marco2306]

Yes, I have GMX, Hotmail and T-Online.

And also to another host provider

Give this the same error? Please check logs again.
And what says telnet?

You will need to write to tosa@rx.t-online.de and ask them to unblock your server IP on their network.
You can also check MultiRBL.valli.org - Blacklist, Whitelist and FCrDNS check tool where else your IP is blocked.

The IP was not blocked by the Telekom, it is due to the PTR record (rDNS).
This was confirmed to me by Telekom and Plesk Support.
rDNS would be changed more than 48 hours ago, now at least a large part of the mails go out.

Does anyone know where to send mail to Outlook (Hotmail) (German) to have my IP unblocked?
There is nothing in the logs ...

If no URL is given in the logs, you can try this:
