I wonder if it's possible to do something like:
ip = static
ip = dynamic, behind router so NAT
main (postfix) --> *@example.org,*@example.com --> zimbra (which handles spam, mailboxes,...)
zimbra --> main
Is this possible? if so how does this work DNS wise?
currently I have example.org has a MX pointing to mail.example.org.
(which currently resolves to the same IP as Example Web Page)
so I want to point mail.example.org to my zimbra server at the office (via cname to my dyndns account).
Will this work? what do I need to do at the zimbra end config and dns wise?
I want the mail to be buffered on the main server incase the one in the office goes down and send once it's back.
I know I'm asking a lot here but the information i can find seems to say it's possible but it's very very confusing.
I haven't done any install yet for the zimbra server.
It will either be a chroot on my gentoo server or a domU on out main server.
So I'm open for sugestions even on which distro to use.
Thanks in advance for any help info.
some extra information:
So far i've used kerio mail server but my companies license is expiring and it's way to expensive we have around 8 active users.
I've no prior experience with zimbra or postfix.
