Hi, I have setup spam filter and opendkim key on our mail server with Postfix,Dovecot and OpenDKIM server.

Following are few lines from dovecot.conf which were added to dovecot.conf. After troubleshooting, we removed the following lines and the login from webUI roundcube started working. Can someone please explain the importance of following lines in accordance with Opendkim? Should we disable plaintext authentication for opendkim to work?

disable_plaintext_auth = no mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u userdb { driver = passwd }

passdb { args = %s driver = pam }

protocol imap { mail_plugins = " autocreate" } plugin { autocreate = Trash autocreate2 = Sent autosubscribe = Trash autosubscribe2 = Sent }

service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl=required

Thanks, Vijay
