Postfix + Dovecot, does not accept letters, where to dig?

Question

Mail server

Good day to all!
A situation happened to me, I set up Postfix + DOvecot, plus PostfixAdmin + Roundcube web tools, all this on Ubuntu Server 16.04
Users are stored in MySQL
There are no problems with sending, but I had to tinker with receiving, and so I did not find a solution
