Mariadb error

[Gift Rain <giftrain01@gmail.com>]

Good day,

I'm running Debian 11 and getting error "Failed to start MariaDB 10.5.12 database server.

My emails are not working. Another error on my logs is : 

"warning:proxy:mysql:/etc/postfix/mysql/sender_bcc_maps_user.cf lookup error for"

Please help,
