Kinda dumb question... SMTP relay

[erock]

I am updating a program I wrote a while ago, and am testing it out. when I do a debug build of it, I have it set to use my credentials to send email from apis networks (note when in production it uses it's own SMTP server) I am using a fake email address for this to send from. when I send to my account on apis networks, it sends fine, but when I when i send to my gmail account i get a relay access denied error. so i am using a different email address but authenticating via my credentials. do I need to create an account for this to work? or is there something I am missing.

Send an AUTH command or use POP before SMTP to authenticate the client with the outgoing mail server.

found the problem actually, I was sending our .com domain as the domain like in kerberos authentication. it didn't like that too much, once i got rid of that it worked fine. thanks for the tips!
