MS Exchange SMTP Settings

[KEN]

Our organization just went to treos for many of the employees. We run
a 2003 MS Exchange box for email.

Treo users can send mail to addresses in our organization but we get
an "The following recipients are invalid:" error any time they send
mail to anybody outside our organization. I can't find much in the
way of support on that error message. It seem like the SMTP settings
are wrong or we can't relay mail to the outside. When using Outlook
or Eudora any outgoing mail is delivered just fine.

Does anybody have any solution to this problem or seen anything like
this before?

Thanks

I think you might want to actually post this over to one of the
microsoft.public.exchange newsgroups.
