These are the compile options for other applications I use with qmail.  
You really need to read the INSTALL files for each of these don't just go 
about it in the blind.  There are users and groups to add and startup 
scripts to be made.  Do not try and run the pop server through inetd it 
just didn't work for me and had permission issues that kept the roaming 
relay from working.
