Hello there, I have a quick question / request for clarification. I’ll try to be concise.
My ISP has a generic rDNS. For clarity I’ll say that it is defined as follows, "Generic rDNS means that a DNS query on the IP address resolves to something like: 123-45-67-8.your.isp.com. The opposite of generic rDNS is a "unique reverse pointer" which is usually something like mail.your-domain.com." Now my postfix always warns me due to this generic rDNS of my ISP. Postfix says, "hostname verification errors in FCrDNS: Does not resolve to address 123.45.67.8 123-45-67-8.my.isp.com” Any free FCrDNS online service also shows and says the same thing, that is that rDNS is not forward confirmed or PTR is generic. The IP address is static. Postfix is working OK but this warning is simply always there as I have no control over my ISP. Would appreciate any suggestions / advices / pointers on how do I fix it? Many thanks in advance! Regards, Dennis.
