Outgoing mail issue

[captain7616]

Hi All,
I am a zimbra newbie, and have migrated my entire mail server over to it, its about 100 users, with about 20 domains in total,

The issue I am having is that I when I send mail it mostly works on most domains, but on some domains it bounces the mail back to me with unable to look up host wlsh.co.za: Name or service not known which is not hosted locally on the server, but 99% of my other mail goes out fine,

I am not using an upstream smtp as I have an uncapped solutiona and the ISP for that dont supply upstream smtp but I am pretty sure I have configured it correctly , when I do a dig of the mx record it resolves with no problem here is the dig of the domain's mx record , also I also run my own internal dns server on another server on the internal network (bind9)
zimbra:~# dig mx wlsh.co.za

Is there possibly a setting or something that I may have overlooked, and someone could assist me, I would be most grateful,

Kind regards

Firstly welcome to the forums

If you could post the following information it would really help us

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes

host `hostname`
zimbra.msits.co.za has address 10.0.200.56

Um, I think I see where the error is .... there is a difference of the local domain being msits.co.za and the zimbra server is on a subdomain of elk.zimbra.co.za , or am I jumping the gun here ?

Many thanks
