Letters from mail.ru do not reach Google Apps mail

Question

Google Workspace

From the beginning of the week, it turned out that letters sent through the mail.ru web interface do not reach the email box on this Google Apps domain.
The error message comes to the sender after a long time (up to a day).
All other letters arrive as usual.

Error message text:

This is the mail system at host fallback2.mail.ru.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

timed out

Where to go?

Answer 1

Do you have all the MX records recommended by Google spelled out and with the correct priorities? The highest priority (i.e. the lowest number) should be ASPMX.L.GOOGLE.COM. A Specified in the letter is in 4th place.

Answer 2

Try mail.ru support.
Just describe the problem in detail, attach bug reports.
They really have a response time of up to 5 days, it seems, and they like to ask questions after this type of “is the problem still relevant?” :)
But practice has shown that solutions to a technical problem like this - habrahabr.ru/qa/14500/ can be expected from them
