Question : Exchange thinkgs email address is spoofed when sending mail from iPhone

I have a guy that has been sending emails from his iPhone forever.  Our smtp server isnt setup, so we use cwmx.com for iPhone users.  He recently got this message.

Reporting-MTA: dns; someones.cingularme.com
Arrival-Date: Sun, 27 Jun 2010 00:58:48 -0500
Received-From-MTA: dns; [ipaddress here]

Final-Recipient: RFC822; <[email protected]>
Action: failed
Status: 5.1.3
Remote-MTA: dns; our.domain.org (ipaddress here)
Diagnostic-Code: smtp; 553 The sender is spoofed.


We have surf control and I am wondering is this caused by surf control, our Exchange or the SMTP relay we use, CWMX.com

Answer : Exchange thinkgs email address is spoofed when sending mail from iPhone

I believe it should be something like (C# only):

1:	User.longVal = (double)CurrentUser.longVal ?? default_value;
