i've Zimbra 5.0.18 on CentOS 5.3 fresh install, yum update, sendmail removed, fetchmail installed, zimbra installed without warning or errors.
I've two big problems:
my office have only a little workgroup (es: MYWRKGRP), not a local domain, but we have a internet domain with a maintainer (es: myinternetdomain.com) and some email address like firstname.lastname@example.org.
I've set up zimbra installation (and centos network) with both configuration: first time centos domain = MYWRKGRP, centos host = ZIMBRA, and the result in zimbra console is a domain = zimbra.mywrkgrp and users: email@example.com.
Second time centos domain = myinternetdomain.com, centos hostname = zimbra (i must give a hostname, it's true?), and the result: firstname.lastname@example.org.
In both cases the generic user mail address is different from the real mail address!
Important: i don't want give to my zimbra box the role of master mail server, i want zimbra box downloading mail from maintainer mail server (pop3) and put them into users zimbra mailbox. And when a user send a mail, i want zimbra relay the mail to the smtp server of the maintainer.
How i must configure zimbra to do these thing correctly?? Help me please!
Bye and many thanks!!
