postfix/dovecot/mysql Not finding local user/domain

Question

linux

I would be very grateful if you could help me fix the error.
The bundle is configured and working, but does not deliver mail to local users. Moreover, if the user is not in the database, then the redirection set to * 123.com works , that is, the letter is received and forwarded to the specified location (the redirection is to an external domain), if the user is in the database, then the letter is not delivered, but I receive it in the logs :
postfix/trivial-rewrite[25066]: warning: do not list domain 123.com in BOTH mydestination and virtual_mai
lbox_domains

Answer 1

Is the transport for the domain specified? It's well described here .
