PTR record vs. Mail.ru
Unexpectedly, I ran into the impenetrability of Mail.ru support. It is understandable, the service is free, but once the support is displayed in a separate unit - it should work, and not just study feedback (my deep IMHO, of course).
Last weekend, one of their customers arranged hosting in a well-known Moscow telecommunications company. A domain was registered at the same time, since the part-time host and the registrar too. It is so convenient for the customer to pay for hosting with a domain in one organization.
The domain was delegated and after a few hours I went to check the validity of the DNS.
Everything was fine, except that the PTR record remained for the previous domain. This happens when a DNS administrator “forgets” to delete a PTR when deleting an account.
A letter to the support and after a couple of hours a notification from technical support fell to the mailbox, that everything was fixed. Well, we wait until the next day, since the TTL for the record is 24 hours, and we check how the mail goes to the main free mail services: Yandex - OK, Google - OK, Mail.ru ...
')
Well, wait another 12 hours. While the essence of the matter, we register SPF, check again - nothing has changed. Well, we write to the support, especially not hoping for an answer, with abuse do not respond soon and not always.
Immediately comes the answer to the robot with a ticket, which is already nice.
A day passes and support, oddly enough, responds. True question: "Specify, please, is there a problem at the moment?"
I answer, yes - nothing has changed. Mail is still not accepted by your server, despite the fact that your local server should have deleted the record a long time ago since the TTL time has expired.
Pass another day. Today comes the answer.
No, everything is clear, we wanted to spit on the TTL of your records, we have our own monastery here, but how can we write about 48 hours in response if 84 (!) Has passed?
And what to explain to the customer who uses mail on mail.ru ...
I am indignant!
PS: I add email headers (RFC 822) of a successfully delivered message to the gmail.com box so that everything can be seen.
UPDATE: Today, March 26, at 12:47, almost after a week (!) Since the change of the PTR record to the correct smtp-server, Mail.ru accepted mail. Here are the headers of the first successfully delivered message:
It would be very interesting and useful, as I and others interested in this thread to receive a comment from an employee of Mail.ru, what was the matter - today in a “lichku” I received a message “Is the mail already going now?” From the employee Mail .Ru Group ...
Official response received. Thank you all for your support, advice, guesswork, and quatro for a detailed and honest answer.
