As mentioned in an earlier thread we are testing a GW8 setup behind our firewall for managers at another company that we are in the process of absorbing. As it's an international domain I had the pleasure and privilege of setting up my own DNS records <g> using's tools.

I provided two A records
@ and www

and three MX records
10 @
20 @
30 @

all pointing to my ADSL ip

In testing we are seing a lot of 420 and 450 errors. I suspect the other company is obstructing us with the firewall but thought I'd check

Does GW expose subdomains? like or Early tests were good, but things like sending attachments seem to mess up.
