Mail problem after upgrading from Debian 10 to 11 output Failed Login!

I upgraded from Debian 10 to 11 and now simply no email account can log in simply gives output of Failed to log in.

If anyone can help me to solve this I would appreciate this !

Have you looked at your logs yet?

Found the problem I just /usr/local/hestia/install/common/dovecot/conf.d # cp 10-auth.conf /etc/dovecot/conf.d/10-auth.conf and fixed my issue ! thank you for the reply !
