Why isn't the letter coming?

Question

postfix

Hello! For some reason I can't receive an email. In the logs of the mail server where the mailbox is located, where I send the letter, I see this:

Feb  2 13:54:36 esk2 postfix/smtpd[27257]: connect from forward4m.cmail.yandex.net[5.255.216.22]
Feb  2 13:54:37 esk2 postfix/smtpd[27257]: 64999C49EA: client=forward4m.cmail.yandex.net[5.255.216.22]

What could be the reason? As I understand it, the mail server cannot find the user user1, but it is registered in the database.

How does postfix go to the database? Give a line from the config.
