Issue rdns

[AlexSchmWebServ]

Server operating system version

Debian 10.13

Plesk version and microupdate number

18.0.56 Update #4

Hey there,

My customer hotel-haus-krone.de receives email errors from certain mail systems saying that the rdns record is not set or invalid.

Mails from all domains are sent via the server's hostname alexanders-web-services.de.
All domains' mx are looking like
mail.<customerDomain>.<tld>


I have already made a lot of changes over the last 4 days in the configuration of the dns zones but nothing worked sothat I am trying to get some help here.

Thank you in advance and best regards,
Alex

rDNS is something that your data center must set for your hostname. It cannot be set on your server.

Okay, thank you for the response.
So in order to have a correct rdns entry for every customer domain, would I need to contact my data center that sets multiple rdns entries? I thought it makes only sense to have one rdns per IP?

Yes, one reverse DNS will do. Normally it is only needed for the mail server name.
