It is your _forward_ DNS which is the problem.
Basically, when you start an SMTP transaction, your system sends
and at that point, many mail servers will do a DNS lookup on
'globeaccess.net' for an A or MX record, to check that the right-hand part
of the E-mail address is valid.
If the DNS for globeaccess.net is not correctly set up, then the mail will
be deferred or eventually bounced.
