weird, never have problem like yours..

- try to use other email client
- try to disable amavis and dkim or any other antivirus, content filter etc, just make postfix sent email directly to other host...
- try to rebuild postfix...

Hi,

Look like your IP from Digital Ocean droplet, as i know, ptr record will automatically created when you create a droplet...
If not DO, then ask vps provider to create ptr record for your IP.

I have a different situation but with the same response.
Gmail is saying I'm missing PTR record but the IP to wich is reffering is the routable IP not the public one. So I asked my ISP to add a rDNS to that IP as well and guess what? Gmail says the same thing.
Now, I'm not some sort of a class A sys admin, but neither a mega-idiot, so, why the hell does Gmail need a PTR record to my routable IP? And much more, this happened two weeks ago all of a sudden. I did not changed anything, I didn't messed up with my courier setup, DKIM and SPF records are there untouched, just that I made an apt-get -y upgrade and it did in fact updated courier and postfix, but, of course, I compared the backup files main.cf and master.cf and nothing changed.... So it's not from the update.
Furthermore, to make it even harder, last week worked..... 50% of the emails went to gmail, rest of them returned. I have around 40 clients, 130 mailboxes, anti-spam filters like a maniac, and the last 3 years the email server worked with no problem whatsoever...
Help!!!! I'm loosing my mind in here.

PS: please don't ask me why I'm using apt under CentOS :)...

let me ask you first, how the world can reach your server?

Is this a real question? First of all, the ROUTABLE IP function as a gateway to and from internet. So it's not mandatory to have a PTR record assigned to it. The PTR is imperative when it comes to the public IP. In cases of a NAT, yes, I agree, the PTR must be assigned to the external IP, but in public subnets I know for a fact is not mandatory to asign it to the routable IP.

And furthermore, the problem is that the PTR is asigned to both the public and the routable IP's and still Gmail says that the routable IP has no PTR assigned.
PS: thanks for the answer.

Oh, and just as a notice: the routable IP in question had a PTR record assigned to it, but to the ISP's domain, not mine. And it did worked fine for almost 3 years. This problem appeared two weeks ago..... and that's what bothers me, because the ISP didn't changed anything to his config, and neither did I....

of course real question, just want make sure you own static public IP. Because google, yahoo, hotmail sometime refuse to accept direct email from non static publick IP, they might also refuse ip with ptr record contain ip/part ip address (eq isp-adsl-110.22.***)

Well, I already specified that on my first post.....
So, anyone, ideas?
Oh, to make it more strange. Since 2 hours ago (and honestly, I'm slightly going insane here), Yahoo started to receive e-mails from all my domains.... What is strage with this? Well, I did not change anything in the settings, neither the ISP, Yahoo received e-mails from all my clients (included my domains) until 2 weeks ago in aproximately 1-2 minutes after sending (a normal e-mail with no attachment). 2 weeks ago Yahoo started to receive the e-mails in 3-4 days after sending them. And from aprox 2 hours ago, my e-mails are received in under 1 minute.
What, why, how, who? Those are the words that keep come into my head..... And Gmail still returns the same missing PTR to my routable IP....
