Postfix does not accept mail from the Internet, but everything is ok with telnet. Where to look?

Question

postfix

250 2.0.0 Ok: queued as 493066079BFA
And it arrives on the box, and when sent from the site mail.yandex.ru postfix stupidly ignores everything. I ran tcpdump and while sending a packet, they arrive on port 25. There is also no reaction to this event in the maillog log.

Logs in the studio. And what does "just ignore everything" mean? There should be some logs if Yandex finds your server. Otherwise, the problem must be looked for at the DNS level.
