SMTP Email Address Size Limitation

I do not believe that I am using Active Directory to do the forwarding. Is
there a way to confirm how this is happening? I have added SMTP to the IIS
services and set everything up there. I do not have a SmartHost identified.
I have also used Microsoft's teing method for SMTP functionality to confirm
what is happening.

I can test the SMTP and it works great until I get to a larger email
address. Is there any way around it? The error that comes back is a 5.0.0
that states the email address is unknown.

Hi,

I have tried this with IIS 6 and found no problem. But this won't help you.
I'm really wondering how SMTP server from IIS 5 CAN know if an address is
unknown! You said you used it as a forwarder host, but if it forwards, it
simply passes the error from a remote SMTP host.

SMTP server can only report unknown addresses if you also integrated it with
a POP3 server. But if the domain exists to which mail is sent, it *always*
drops the mail in the inbox for the specific domain.

Regards,

Egbert
