And since no one else has mentioned this...some of us don't use /etc/passwd for 
authentication. So searching /etc/passwd would not work anyway. Isn't there a C 
function call to check user/group id? Or at least a universal alternative...

I'm pretty sure there are RPMs that handle this situation already.  How
do they do it?

I'm not sure if this would be considered an improvement.  Parsing /etc/passwd
every time a vpopmail binary is invoked could be expensive on some systems.

I'm looking at adding a configuration file to vpopmail for the 5.5 branch that
will contain all the stuff that usually you have to set at configure time.  The
UID/GID would be contained here as well, but that's not currently available.
Just an OT about the config: It will be compiled so as to be very quick to load.

Thoughts anyone?
