Can i have multiple ptr records

Logout Register. Discuss your pilot or production implementation with other Zimbra admins or our engineers. Can anyone explain to me the correct approach for the following: I have: PTR XXX that resolves to mail. PTR will not reverse to any of the domains below: mail. You do not have the required permissions to view the files attached to this post. Is it something completely different? I am pretty sure that this has already been discussed, but I did a lot of research and nothing I found could help me understand what needs to be done.

Please excuse my asking such rookie questions, I know they may sound "stupid" to most of you, but I am just starting with my DNS journey and I feel a bit lost so far Thank you in advance! Probably only forward lookups are delegated to your server, so you have to set the reverse DNS somewhere in your provider's hosting settings. You'll need to contact your host and have them change the rDNS record.

The rDNS doesn't apply to the sending domain, rather the host name of the server. If the hostname is wondergreece. Rasp Regular Pleskian Plesk Guru. So in your case the host wondergreece. For this PTR type records are used. This where it can get a bit confusing, because you can create PRT records in Plesk. But in almost all cases this won't do anything for you. You are most likely just a user of a IP address, owned by your provider.

So you'll have to set the reverse DNS trough your provider. Usually they provide some control panel for this basically what mow also wrote. You only need to define the reverse DNS for the hostname of your server. Not for individual domains. Rather use a subdomain as the hostname for your server.

George, We do have a few domains with multiple MX records also ours being one but thinking that would be a different issue. George wrote: Again I find my self chasing Martin around the community. Cleaning up your DNS both forward and reverse is the correct step forward.

PervonZweigbergk This is not what I asked, but for example, because I have several names pointing to the same IP, and want the reverse to match all of them. PervonZweigbergk Imagine a mail server that handles mail for multiple domains. You may want to use a name within the domain you are sending mail for in the EHLO command. Certain receivers require that you have a PTR record matching the domain in your EHLO command, otherwise they won't accept mail from you.

But if you have multiple PTR records, they may just pick one of them at random, and if that one does not match the EHLO command, it rejects the mail. I know it's not what you asked, which is why I asked this via a comment, not as an answer. You'd do well to be more explicit that you're talking about the context of outgoing e-mail, which is what kasperd is speculating. A mail server is only expected to use a single name in its EHLO commands, regardless how many domains it handles mail for.

Elaborating on "one canonical name": in cases where the IP address could be associated with more than one entity, the most specific is preferred. In the case of a webserver with multiple name based virtual hosts, the name of the webserver itself is most appropriate. It looks like a de facto rule, as software developers started to consider that only one PTR was the norm.

Am I right?
