Hello, I am having a problem with a Ubuntu server with a dovecot error: [login to view URL] - LSB: Dovecot init script Loaded: loaded (/etc/init.d/dovecot; generated) Active: failed (Result: exit-code) since Wed 2021-05-12 13:24:29 CDT; 15min ago Docs: man:systemd-sysv-generator(8) Process: 14495 ExecStart=/etc/init.d/dovecot start (code=exited, status=1/FAILURE) May 12 13:24:29 [login to view URL] systemd[1]: Starting LSB: Dovecot init script...
