I finished installation of Zimbra 6 on CentOS 5. One of my customers has some special requirement, I'm wondering anyone else can give me some support/tips/hints. I'll describe the detail situation here:
One person ( called Tom, email: email@example.com) has his seperate mail server (mail.abc.com) which is the domain's MX record as well and has a lot of other users (e.g. Peter); What we want to do is that create a new domain (abc.com) on our zimbra server and create only one account - firstname.lastname@example.org, use fetchmail to get his emails from the real mail server; And he should be able to send to email@example.com which hosted on their real mail server. How to make it happen?
I did set up the SMARTHOST (external SMTP relay) on the Zimbra Web Admin; Not really work; From internally the emails from firstname.lastname@example.org to email@example.com will first send from localhost (127.0.0.1) smtp server, then to external smtp relay server; The result was that Tom always got a emails saying the target username not exist: I guess it means it could not find peter on local zimbra server.
I'd like a solution maybe without SMARTHOST setting since we have other domains hosted on our server and I don't want it apply globally.
Any good suggestion/work around?
