double checked the master.cf and nothing is chrooted.

i don't think it's a permissions error since i can send external mail to my
gmail account or other domains, it just seems this one domain is giving me a
problem.

i just tried a simple telnet on port 25 to the 10 MX record, and it did take
QUITE some time for it to respond, is it possible that it is timing out?
