I am sending mail to a wirking mail account on another service. The mail is returned as undeliverable: invalid user id. I can mail him from any other server but my imail server and he gets the mail. What could cause this? j.m. Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
