Migration Postfix to Zimbra

[upanwar]

Hi,

We are currently using postfix mail server and we have a centrel LDAP server(Fedora Directory Server 7.0) which have different OUs and accounts, for mail and system login... I wish to shift our mail server on ZIMBRA and want to add mail user (OU=mail) only to ZIMBRA... so can any body help me for the same.....

One more thing i have seen that if i telnet on our ZIMBRA server (the test mail server) on port 25 from anywhere... i get access and send mails through mail commands without authentication to local users..... is it a bug?? or i have to made some changes...

waiting for your early response.

Regards
Umesh
