mail() and Postfix

Can't send from either sendmail or postfix

[HeadBut]

Mac OS X Server 10.2 or 10.3 I can't get the sendmail to send on the OS X server but the mail() returns true. And I can't find any examples of wrappers for Postfix on 10.3
Has anyone gotten email (php's 'mail()') to work on postfix mac 10.3 or os x server 10.2

Are you sure that sendmail is actually working outside of php?
Is it possible that something inside of your mail() function is not put in correctly? Can we see the code you are using to send the mail?
Are you sure that you have the corrected setting for sendmail in php.ini?

Have you checked your mail logs?
*BSD, they're in /var/log/maillog

try mailing yourself from the commandline using:
"mail [e-mail]"
