Configuring Apache to use my smtp.

[Mhtml]

Say my mail server is mail.xyz.net.au how can I configure apache to use that?

I've edited the ini file where it had localhost to mail.xyz.net.au but I still get an error when trying to use mail().

The error is "unable to connect to smtp server" or something similar..

Thanks in advance :)

Is this smtp server on your machine or a remote machine? Does it require authentication?

[Mhtml]

It's remote, and it would require authentication.
A username and a password.

TIA Spookster. :)
