this morning I noticed not getting any email on remote to server mail client, though, in webmail/squirellmail on mail host there were new emails
restarting with doveadm stop/dovecot 'fixed it' what could've gone wrong, what to look for in the logs ? thanks for any pointers long running dovecot/postfix/mysql setup dovecot --version 2.3.14 (cee3cbc0d)
