rDNS and Plesk

[omexlu12]

Hello,

Because GMX and WEB block generic rDNS like XXXXXXX.yourvserver.net i want to change the rDNS now that the mails to GMX and WEB can get submitted.

Now my question:
I have a A-Record (mail.domain.tld > SERVERIP), is it now enought to change the rDNS on my provider panel or i need also to change some configs in plesk panel oder config files?

What exactly must i do now?

Thanks in advance.

My Hoster is Strato, so i have only to change the DNS-Reserve in my Controlpanel from xxxxxx.stratoserver.net to mydomain.de?

You need the following:
- A-RECORD (example: mail.domain.tld) pointed to your serverip
- change the hostname in plesk panel under settings
- Change the DNS-Reverse to this domain (mail.domain.tld)
- ajust if needed some DNS settings

After that wait a bit (max. 24-48 hours, maybe earlier) and the mails gets accepted by GMX and WEB

PS. Sry for my bad english, i hope you understand

@omexlu12,

In essence a "golden oldie", i.e. an old and known solution.

However, in the whole process, there has been some error in the line of reasoning: it is not about a correlation between rDNS and mail (in general) or mail.domain.tld (in specific).

In essence, all that you have to do is the following:

- use a domain that is owned, registered and manageable by you,
- create a subdomain, with an A Record pointing to the IP, assigned to the server,
- use Plesk Panel to change the hostname to the (full) name of the subdomain (note: the use of the Plesk panel is convenient, since it will make the hostname persistent across reboots)

and this way, one realises a solution (similar to your solution), that is "fairly clean".

Reverse lookups by means of PTR records are then handled by the servers of the hosting provider, while the A Record is allowing mail servers to do a "normal" association of IP and the sending mail server, as required.

Finally, note that you wouldn´t have this problem if the hosting provider would have configured the routes of mail traffic properly.
