So...
Other computers on the LAN need to be able to ping mail.domain.com and it resolves to the Zimbra IP
-or-
The Zimbra machine needs to ping mail.domain.com and it resolves to the Zimbra IP
Is any of that correct? Struggling here :(
cheers, B

Basically yes, your DNS setup has to be in good working order. The only other problem you will have with OpenVZ is the hosts file format may need to be changed. When you install Zimbra, it will complain about the hosts file. Make sure you change it to the format suggested.

I've been struggling with named.conf and db.domain.com zone syntax all day but finally got there... so I'm ready to install Zimbra!
dig -t mx domain.com
Returns an answer section of mail2.domain.com
dig mail2.domain.com
Returns an A record with 192.168.1.4
nslookup domain.com
Returns 192.168.1.4
Each of these guides express the zone syntax in a slightly different way

I do now know Bind's zone file syntax pretty well ;)
I also understand why all this needs to be done... if I send to joe@mydomain.com from Zimbra, we don't really want Zimbra firing it out onto the internet for it to have to just come and be processed by the same server!
Final question... I'd like some confirmation on what I should set for the values of the timeouts in the SOA record?
Currently I have:
$TTL 4h
Refresh 12h
Retry 1h
Expire 14d
Minimum 1h

Easy confirmation of your DNS is the following commands (run on the Zimbra server):
Code:
cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com mx
dig yourdomain.com any
host `hostname` <-- use that exact command with backticks not single quotes
I don't use bind any more but you may find webmin useful for managing your server (including BIND).
