I can not use addresses in a realistic manner -- we have so many different IPs from different state agencies that it is not realistic approach. > If you use "No mail relay", everyone > must use SMTP AUTH to relay mail.

I have tried "No Mail Realy" and enable SMTP AUTH however, when I do this ALL out going mail fails to be delivered with this error: The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[EMAIL PROTECTED]'. Subject 'test3', Account: 'mail.esd112.org', Server: 'mail.esd112.org', Protocol: SMTP, Server Response: '550 not local host hotmail.com, not a gateway', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79 When Imail was first installed with was give the name "mail.esd112.k12.wa.us" -- our domain was later changed to esd112.org. Is this somehow related to the problem? Thanks for your help!
