Thanks for the reply. Yes, I have attempted to enable SMTP Authentication via the Host section. I need to enter the (1) SMTP Server name, (2) SMTP Authentication (radio buttons...(Anonymous, Basic, or NTLM), (3) SMTP Username, and (4) SMTP Password.
I'm assuming (1) my mail server, (2) basic authentication, (3&4) webmaster email account...but have not been successful. I am wondering if I need to force Port 587 somehow. Any assistance appreciated...
