Exchange guru wanted: Apply within

I have a user trying to send an email to an external domain, say receiver.com. When she tries to send the email using her Outlook (She is VPN'd in to us) she gets the email rejected stating that she is not permitted to send to that recipient and in the exchange logs it is showing up as :

     OutboundConnectionCommand SMTPSVC1 EAIG2K - 25 MAIL - FROM:<[email protected]> 0 0 4 0 516 SMTP - - - -
 2005-06-09 22:00:30 <receiving IP> OutboundConnectionResponse SMTPSVC1 MYEXCHANGESVR- 25 - - [email protected]+OK 0 0 41 0 610 SMTP - - - -

 2005-06-09 22:00:46 <receiving IP> OutboundConnectionCommand SMTPSVC1 MYEXCHANGESVR - 25 QUIT - - 0 0 4 0 16860 SMTP - - - -

Now, the odd thing is, when she sends the same email through Outlook Web Access, it works fine. I've check all of the settings that the MS KB articles tell you to check and all are correct. Another one of our users had this same issue several months ago while sending to the same domain and same receiver but it seemed to resolve on its own.

Any thoughts or suggestions ?

TIA.

I had several remote domains that I was having intermittant problems sending to. (same error, "You do not have permission to send to...")

Fortunately my ISP provides a "smart host" service, so I just had email that goes to those domains use thier "smart host" (a custom connector in SMTP)

Not sure if that would help with your problem, but it might be worth a try.
