Can't receive emails to my mail server
Found this solution:
add this on /etc/dovecot/conf.d/20-lmtp.conf:
protocol lmtp {
postmaster_address = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf # required
mail_plugins = quota
}
probably this was:
protocol lmtp {
# Space separated list of plugins to load (default is global mail_plugins).
#mail_plugins = $mail_plugins
}
