comment Outgoing mail fails to be received by Gmail. Rejected because PTR record does not mach forward lookup
I waited, and now it works, again, it was strange to me because the mails were never rejected for that reason before. But the way I see 'My IP had an OK reputation before, it was blocked. So now it is treated differently, the improper PTR that was setup before did not cause an issue because the IP had a better reputation, now it is being treated differently so this caused the old improper PTR to be rejected, I corrected it and now It is working'. Thanks P.S: When I said they don't respect TTL, I meant they usuallygo for lower TTL than what is actually set, in my experience that is.

It is working now, it was strange as this PTR was setup for a while, as is! And now suddenly it needs correcting : ) Even though Gmail did not implement any new policy, either way the problem is solved by correcting the PTR to one that will resolve back to that IP address

I've come to realize popular providers such as Gmail do not necessarily respect TTL, but the thing is, this PTR has been setup for a long time, except it pointed to a hostname that does not resolve back to the same IP. So unless Gmail has implemented a new policy in this regard, TTL should not be the issue, either way I will have to wait and see how this goes.

I do, my provider's control panel allows me to update my PTR. And I checked it from an external server, it does resolve to the set host name

comment How do IPs end up on the spam blacklists
Spamhaus blacklisted my IP because another IP on that subnet was sending out spam, I can be sure of that because before yesterday that IP was never used, and it was not blacklisted, today it is! And because the other IP sent out spam, this clean IP was blacklisted as well. I read on "another" blacklist that the blocking is because a "neighboring" IP sent out spam, so I assume that was also the reason why spamhaus blacklisted my IP.

As it turns out, the whole subnet is blacklisted! I will do my port and try to limit spam from my IPs, but this spam issue is such a hassle really. Thanks for the info though.
