From dovecot.conf :

Valid UID range for users, defaults to 500 and above. This is mostly

to make sure that users can't log in as daemons or other system users.

Note that denying root logins is hardcoded to dovecot binary and can't

be done even if first_valid_uid is set to 0.

#first_valid_uid = 500 #last_valid_uid = 0

Have the following entries in dovecot.conf

auth_userdb = passwd-file /etc/dovecot-passdb auth_passdb = passwd-file /etc/dovecot-passdb

auth_user = dovecot

passwd-file is owned by user and group dovecot

When I try to log in .. I get

dovecot: Feb 19 16:41:30 Error: Logins with UID 0 not permitted (user echo) imap-login: Feb 19 16:41:30 Info: Internal login failure: echo [127.0.0.1] dovecot-auth: Feb 19 16:41:30 Info: Login process 12 disconnected

Any ideas ?
