Hello Blues,
I have a situation that is puzzling me.
I have two BQ Servers on two different subnets (I am migrating to a new data
center). I migrated a site and now users on that site cannot receive e-mail
(user unknown). Here is a sample of the output if I try sending e-mail from
the old server (to simulate external users which are already reporting
inability to send):

I also have a Barracuda SPAM firewall appliance. It is configured to send
mail for a particular domain to the machine that domain is hosted on. This
has been my configuration for 2 years standing. Doing a test mail from it
yields good results too:
Successfully sent test message:

The DNS is configured as such:
[root@baraka ~]# nslookup
> set type=mx
> icpm.us
Server: 64.182.137.5
Address: 64.182.137.5#53
icpm.us mail exchanger = 20 barracuda.muntadanet.com.
icpm.us mail exchanger = 50 www.icpm.us.
Any ideas?
