I have had great success sending mail when I SMTP to the actual mail server that the email address is on. But when I try to send from my server to some other email address I get an unable to relay "email address" server response. If someone has any ideas on this I would appreciate it. I have included some information that may aid in this endeavor. (I do not want to use Active X thanks to Outlook's dislike of that)Example:Test@bellsouth.net email to mail.bellsouth.net works fine. Test@company.com email to mail.company.com works fine. Test@bellsouth.net from mail.company.com gives unable to relay message. (Vice Versa)Exact server response from SendEmail_LV6.vi from developer zone: (http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3EB9956A4E034080020E74861&p_node=DZ52050&p_submitted=N&p_rank=&p_answer=&p_source=External)220 server.company.com Microsoft ESMTP MAIL Service, Version: 5.0.2195.5329 ready at Fri, 23 Jan 2004 10:27:22 -0600 250 server.company.com Hello [10.1.1.176]250 2.1.0 test@company.com....Sender OK550 5.7.1 Unable to relay for test@bellsouth.net554 5.5.2 No valid recipients500 5.3.3 Unrecognized command

The SMTP server of my Outlook is mail.company.com. I tried the OpenG version and get the same "unable to relay" error.
