>I think I have gotten this error in the past when my program put a person's name in as the send_to versus their email address.


OK that put me on the right track. We pull the information out of an Access table that is managed by someone else. This person thought it would be OK to put TBD as the e-mail address until the received the real one...

I guess the heart was in the right place.... To bad my hair is all over the floor :)

Thanks Guys...
