It does have to do with Windows SMTP not being configured as an open relay by default (thank goodness). there is a setting in IIS to configure which hosts are allowed to send mail through the SMTP server. You have to add the IP address of the web server to that list.
On a Windows Server 2003 box, open IIS Manager, expand the server name, right-click Default SMTP Virutal Server and select properties, go to the Access tab, then click the "Relay" button. Add the IP Address and voila, it should start working. (Notice the "should" verbiage because it's never this simple :) Aaron Throckmorton _______________________________________________ UPHPU mailing list [email protected] http://uphpu.org/mailman/listinfo/uphpu IRC: #uphpu on irc.freenode.net
