Issue postfix-srs sporadic threw command limit time exceeded

[beli3005]

Hello!

Since yesterday we have some notifications:
Remote Server returned '< #5.3.0 x-unix; internal software error>'

In mail.log on ubuntu 18.04 you find:
postfix/spawn[15218]: warning: /usr/lib/plesk-9.0/postfix-srs: process id 15219: command time limit exceeded

I have no more clues where to search 99,99% of all mails are delivered succesfully.

Any hints?

This behaviour reported was analyzed by our developers in the scope of PPPM-9491
They confirm that this behaviour is standard for Postfix and does not affect any functionality.
They also confirm that error reporting is a little bit delusive.

Hi!
That was an very interesting issue.

gmx and web.de mails was affected.

We had configured two dns servers on our machine. One of them was dead and not more responding. Our carrier missed to notify us.
The DMARC and DKIM check from PLESK was causing this issue due to the non-responsing dns server.

Greetings

See reply #6
The "Host" where Plesk-Mailservices was running on had two dns servers configures. One of them wasn't responding.
If we had the same issue your DNS-Servers configured (or one of them) on that machine doesn't work. Also you can disable DKIM and DMARC.

I must keep dkim and dmarc for my mails service to be received/accepted by mailboxes.

How did you find your dns troubler?

 

[beli3005]

you have some dns resolvers configured on your host-server.
these you can query.
