mail "relay this error - xER41300"

[johnwchen]

our smtp reply doesn't require user authentication to use. No user account is created on the smtp server. Is there a way to bypass this? I tried using my email and passwd in the mail_user and mail_pw field, but still no luck. I tried leaving them blank and using just mail_port = 25...still fails.

Thanks

I have the same issue. We have a local smtp server that doesn't require authentication. Without a username and password it generates "relay this error - xER41300" on every page.
