[PHP email form with Citadel, no sendmail]

ok guys, not sure where or how to ask this so let me start with my config. FC5, apache 2.2, PHP 5.1.4 and Citadel Email server 6.82.
I have a php contact form on my website that worked fine with PHP 5.1.2 (i think),apache 2.0 and the same email server on FC4. Now that I have reinstalled and setup everything again, my php form acts like its working, but the email doesn't come through.
Citadels website says I can make a symbolic link from /usr/sbin/sendmail to /usr/local/citadel/citmail which i did. I can watch the activity in a terminal and ctiadel recieves the message and shows the following:
SMTP: LHLO x
SMTP: MAIL From: xxxxxxxx PageReply-To: xxxx@abc.net
SMTP: DATA
SMTP: QUIT
purging session x
RemovingContext() session x
Performing SMTP Cleanup hook
Calling logout
Session ended.


Any ideas what's going wrong here, or what I'm missing? Any way to work around this? Thanks.

Joe
