mail() on Mac OS X

I have been trying for months now (on and off) to get mail() working in OS X. I have trid various things, but this is my current setup. If you have any suggestions or if you could put me in the right direction, then I would be glad. - I am using PHP v4.0.6 on Mac OS X 10.1 (pre-compiled with cool options from entropy.ch) - I installed Communigate Pro (a mail server -- and this works when I use it in Mail.app) - I don't want to use sendmail, I want to use the mail server I have already installed. - I have these two lines in my php.ini SMTP = ifunk.dyndns.org sendmail_from = adam@adamroyle.com my sendmail_path is still the same as default... but I was just thinking that PHP would use my smtp server....(ifunk.dyndns.org) Can someone slap me in the face if I'm misunderstanding something, or help me if you can. Thanks, Adam.
