Problem with email after restore backup

Hi all… i have a problem with email…
After migrate from a old server with ubuntu 16.04 and vestacp to a new server with debian 10 and hestiacp… create plans and restore backups… i have a problem with my own domain when i try modify my account


HestiaCP says that my domain is unknown domain…

Does /usr/local/hestia/data/users/{user}/mail.conf exists and what is the value in there?
