I've got a (probably simple) question, but I think I have to discribe the environment first.
All members of our organization got 'official' email addresses like
Mails (of my Zimbra-users) are delivered via two relay host to
[ Firstly: organizational centralized mailrelay, which is resposible for all users "firstname surname" (MX for organizationalMXdomain is pointing to this host).
Secondly: mta of my department, where all accounts "loginname" are known. Some of these are Zimbra-users, which mails are forwarded to "zimbrahost.dns-domain" (via SMTP, too) ]
Zimbra-Domain is equal to canonical hostname "zimbrahost.dns-domain", and no MX for zimbrahost.dns-domain exist.
I didn't configure "organizationalMXdomain" in Zimbra, because only a small part of all users in "organizationalMXdomain" are members of my department an only some of them are Zimbra-users.
Most of all mails in our organization are delivered to other mta-hosts.
How can I configure Zimbra to publish only the 'official' addresses
Normal Mailing works fine. (configuring return address / made some address rewriting in relay hosts)
The big problem:
Zimbra uses it's own account names ("firstname.lastname@example.org") in appointments for organizer and members. Other (external) Clients see this as email addresses, and are confused because these "addresses" are not working at all (outside my department).
I tried setting "Display Name" to the official email address, but it has no effect to this matter. (What else could this setting be good for?)
I think there must be a simple way to resolve this, but i can not realize it.
Thanks for any help.
