Hi Friends, I'm running postfix 2.2.10, dovecot-0.99.11 and openldap -2.2.13 in my organization. Here, all my postfix, dovecot, saslauthd, depends on ldap only. Means ldap is acting as a centralized database for user information. In this picture everything is working fine except user login to dovecot for downloading their mails. Actually they can't able to login to the server from client like outlook express. Instead thay are geting error like "server closed the connection...". Here i'm attaching my dovecot conf file and error log. Kindly give any suggesions where i'm making mistake.
