I just upgraded my Dovecot IMAP package on my mail server and when I restarted the service, I got the following warnings... doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:12: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:14: passdb pam {} has been replaced by passdb { driver=pam } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:16: userdb passwd {} has been replaced by userdb { driver=passwd } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:18: auth_user has been replaced by service auth { user } The list was much longer but I was able to self resolve them. I was wondering if someone here can assist me in converting my 'dovecot.conf' file? Below is how my dovecot.conf file appears: protocols = imap disable_plaintext_auth = yes log_timestamp = "%b %d %H:%M:%S " mail_location = maildir:~/mail auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client user = postfix group = postfix mode = 0660 } } } ***doveconf -n*** [root@mail /]# doveconf -n # 2.0.1: /etc/dovecot/dovecot.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:12: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:14: passdb pam {} has been replaced by passdb { driver=pam } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:16: userdb passwd {} has been replaced by userdb { driver=passwd } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:18: auth_user has been replaced by service auth { user } # OS: Linux 2.6.35 x86_64 auth_mechanisms = plain login mail_location = maildir:~/mail passdb { driver = pam } protocols = imap service auth { unix_listener auth-client { group = postfix mode = 0660 user = postfix } user = root } userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep }
