Dovecot not creating folders?

Question

Mail server

Hi all!
There is a Postfix + Dovecot mail server, PostfixAdmin web tools, RoundCube
Filtering is also configured through Spamassasin, ClamAV
Two mails are created, for example:
@ site1.ru
@
site2.ru
site2.ru timeouts fly out, at the stage "connecting to site2.ru"
From the dovecot logs, I realized that folders are not created Tell me
what could be the problem?
In the logs /var/log/doevcot.log such entries
