The first ini_set variable you're setting I believe will only work for a
Windows server.

Aside from that, yes SELinux does prevent the mail command from sending
mail by default. I'm using Fedora 11, so I assume it will be similar;
there are config tools for setting SELinux policies, or you could even
turn it off (not advised on a live server). As a test, try turning it
off temporarily just to see if it is the culprit, then you can determine
what policy changes need to be made.
