I do not know whether Yandex mail and Razor2 are related, the problem of non-deliveries not related to spam obviously cannot be related to Razor2. The background is outlined below.
Today an Über-manager came and complained that their manual mailing gave out a lot of undeliverables , you need to analyze what the problem is and solve it.
After looking through the list abuse-
, there was nothing unusual: nonexistent / overflowing inbox receiver, everything is as usual.
However, checking the headers of the received letter in Yandex mail, it was found:
X-Yandex-Spam: 4
4 days ago, I already checked similar letters through mail-tester.com , he gave a rating of 10 out of 10, that is, everything is fine, not spam.
I had to check the emails for spam again using the above service, and came across problems:

carefully check the contents of the letter (yes, it was necessary initially, but it happened)
at the beginning of each day, before sending template letters, check such letters through the service, for example, the same mail-tester, and if problems are found, send the problem to the solving department
