rDNS/PTR check for IP 192.168.1.150 = not found!
« on: July 04, 2018, 03:11:55 PM »
How can I fix this? 

Your Hostname is: srv.XXXX.net and it resolves to IP: 173.XX.X.211 [Check Black List]
rDNS/PTR = 173-XX-X-211.client.mchsi.com SUCCESS [Check SenderBase]

**Above shows "SUCCESS"** but then below shows this (and why is it checking my LOCAL IP?)

rDNS/PTR check for IP 192.168.122.1 = not found!
rDNS/PTR check for IP 192.168.1.150 = not found!

******************************************************************************************************

I have tried manually adding a PTR record to srv.XXXX.net 173.XX.X.211.in-addr.arpa
(i don't know if i did it correctly, but nonetheless, it still shows that 'error') ~ or is it a 'glitch'?

*******************************************************************************************************

Advice on resolving this (step by step) as i am not real comfortable fidgeting with DNS much. :)
My system works fine, all sites are online, etc.. just this 'error'.

Thanks in Advance.

Hmm, I could be mistaken, but i think that the rDNS/PTR for a LOCAL IP, needs to be changed at The I.S.P. (Internet Service Provider)'s END.

If any one else knows different, please feel free to reply.

Thanks!

sure, thanks.

it's listed under:

[Change Hostname] and [Postfix Mail Server Manager}

----------------------------------------------------------------------------------------------------------------------------------------------------------
Change Hostname
Don't forget to rebuild the mail server with the new Hostname.
Hostname should be only as a subdomain, like: srv1.mydomain.com, please don't use cloudflare protection with hostname as this will cause you issues.

Hostname change will also generate a new Hostname autoSSL Certificate.
Certificate Path: /etc/pki/tls/certs/
Key Path: /etc/pki/tls/private

Your Hostname is: srv.XXXX.net and it resolves to IP: 173.XX.X.211 [Check Black List]
rDNS/PTR = 173-XX-X-211.client.mchsi.com SUCCESS [Check SenderBase]

Any Ideas?  (i'm thinking it is an ISP call).. worth a second option (or more) though.

@24x7servermanagement, you have one AWESOME website!!!   8)

did you create that? or did you hire someone?  I may be interested in something similar (eventually)..

Thanks!!
