Rich,

Are you sure that THEIR SMTP server is not blocking the address "orders@*" ?

As an example, I block the following:

anyone@*
noone@*
someone@*
anybody@*
friend@*
somebody@*

So if somebody@ourDomain.com tried to register on you service, when you mail server attempted to sent the registration code, you would get a bounce back

Below,  I tried to mail to that IP by using one of the domains hosted on it:

The original message was received at Thu, 16 Oct 2003 22:08:25 -0400
from smtp.mags.net [66.181.192.64]

   ----- The following addresses had permanent fatal errors -----
<orders@christianparentalrights.com>

   ----- Transcript of session follows -----
... while talking to christianparentalrights.com.:
>>> RCPT To:<orders@christianparentalrights.com>
<<< 550 unknown user <orders@christianparentalrights.com>
550 <orders@christianparentalrights.com>... User unknown

Not sure any of this help or even applies but ...

Dan S.

that particular domain, probably doesn't have a nobody set up to accept it. It's a new domain.  try something at scrapbookingdepot.com

Thanks,

Rich

That worked... but.. would it have anything to do with the fact the return address is just "postmaster" and not a valid email address? 

Either case.. it doesn't make sense why It would work normal on 2 different servers hosting many domains, an not another server hosting many domains.

Thanks,

Rich
