Hi,

I am trying to send out emails from the FS Server using our mail.myserver.net.au mail servre. Though i get an error as such...

Warning: mail(): SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in c:\program files\firstspot\authserv\upgrade\sendmailp.php on line 238

Any ideas what could be causing that?

It looks like it is problem in your SMTP server. The description of the problem is described in http://cr.yp.to/docs/smtplf.html .

Actually, there are many reasons that a SMTP server fails, such as:

1) if you send from the client PC, make sure you login using FirstSpot's web-based authentication (i.e. captive portal) first.

2) many ISP blocks port 25 to prevent spams

3) the infamous TCP DNS problem. See http://support.microsoft.com/default.aspx?scid=KB;EN-US;263237 for details. Note the FirstSpot DNS server supports TCP DNS queries.
