UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support SMTP on Win2k Server

I have UBB.classic 6.3.0.1 installed on Windows 2000 and am trying to get it to access the SMTP server, but the web server I am running it on is behind a firewall and they Admin doesn't want to enable Relaying from all addresses.

I found the IP that it is using to access the SMTP server in IIS5, but it comes up with the following message when it tries to access the server:

550 5.7.1 Unable to relay for <email address deleted>

The SMTP server has rejected the email address the UBB tried to send mail to.

Please ensure that the UBB is allowed to relay mail through the SMTP server, and that that the From: email address (email address deleted) is a valid email address from this domain.

Thanks.
