MS has your knee jerking to their coroporate policy. :)))
>Sorry, the day got pretty crazy and I must have missed that message. I guess
>I don't understand why the official host name must be a fqdn
it�s a rule, follow it.
>is it a requirement of the internet mail standards?
mail servers take the FQHN in @recipientdomain and try to find out which ip
to send its mail to.
When the mail arrives at that ip, the receiving mail server looks at the
SMTP envelope @recipientdomain to decide whether to accep the msg or not.

that will do

registered with whom? in DNS, only NS hostnames have to registered.
In Imail, there is no such thing as "registered" hostname, only the FQHN
for mail hosts and their mail host aliases.

some do, most don�t.
Don�t worry about that now. When you�r ready, read

your myvasp.com DNS situ is pretty sucky. bad delegation, and NS�s not
responding. syntax errors in the SOA record, only one NS in myvasp.com zone.
cbs4u.com is worse.

not if your firewall dudes know their job.

that would help

no, port 25 is fine.
I�d say you have firewall pb�s, and DNS pb�s to clear up.
Comparatively, Imail is easy.
