Thanks for the answer. As you remember a week or so ago I was struggling with PayFlow Pro and you've been a great help to fix it. Since I reconfigured and recompiled php so many times, I am not really sure if Sendmail was installed or not. Is it possible to see this in phpinfo.php?
Can you please take a look at www.rcbazaar.com/phpinfo.php
Hope I don't have some really weird stuff in there.
