I have configured zimbra-4 OS on CentOS 4.4. Zimbra using external LDAP server for authentication. The problem is that each of my LDAP users 'cn' is different than their email addresses. So there appears a mismatch database search. So i configured in a way that each of my SAMBA users added as zimbra users in zimbra, and each of them added alias as their original email id. For example my SAMBA-LDAP user "test" having email id "email@example.com" is added in a way that user "test" having one alias as "firstname.lastname@example.org". Its working fine .
The problem is that the user "test" sending a mail to anyone, it showing from as "email@example.com" instead of "firstname.lastname@example.org". Is there any possibilities to show the sender address as alias. Help me in this case pls..
