This is an illegal MX record. The MX data must be FQHN, not ip address.

at this point Imail's SMTPD server has identified the domain 
zivsmilestudio.com and perhaps the user (Imail won't care about user 
if nobody alias exists for the domain) and so has accepted the mail 
and queued the msg.

0 = general unknown failure (Should never be seen)
1 = delivered
2 = returned with error
3 = queued for later delivery

I would have thought that the Imail SMTPD server, if the host was 
unknown, would have rejected the msg, rather than queuing it.

>The DNS record has an IP # versus a FQDN, could this be the problem?

The "SMTP client" sending the mail accepted the illegal the ip 
address to find Imail, so that's working. But fix your broken DNS.

It sure looks like the Imail SMTPD server has found 
<[EMAIL PROTECTED]> as a local account + domain. Kinda hard to 
say why when SMTP client picks up the queued msg that it's not 
delivered.  I didn't get any bounced msg back.  What does Imail say 
to postmaster?  Do you have a nobody alias on that domain?
