Good day. Two days one mailbox spammed very strongly. All have been identified. We did all the tests of the mail server. Everything is set up as it should. All tests pass. But the error still remains. Mail is not sent to gmail, although it receives.
Spam started on the 15th, 16th, 17th. Treated. Since then, the post office has not been working. Searched the entire internet

Tidy up DNS records. Changed PTR from mx0.gb2bel.ru to gb2bel.ru
Swears on reputation all the same. =( I don't know what to do.
