Just to restate myself - I'm really loving dovecot, it just flies :)

Well the way I read configure --help is this:

--with-ioloop=IOLOOP    Specify the I/O loop method to use
                          (epoll, kqueue, poll; best for the fastest 	
	                   default is poll)
  --with-notify=IOLOOP    Specify the file system notification method to
                          (dnotify, inotify, kqueue, none;
                           default dnotify if compilable, otherwise

If I don't specify anything, I should get 'poll' and 'dnotify' - if
FreeBSD supports it - or 'none', respectively.  
On my FreeBSD box, I get kqueue and kqueue.

I don't know or understand what the differences are - but it seems to me
if configure followed what was documented, there wouldn't be these
kqueue issues on BSD.   Changing configure to work as documented, would
essentially fix that issue.

The only reason I suggested selective compiling is to help with the
config file.  It has so much to it, if you were able to reduce the
'unnecessary' bits based on the configure line, it wouldn't be so
overwhelming.  Look at the last post where the user had about 12 'real'
lines to his config file.   My modified one (comments and extra stuff
left in there) is 1000 lines.  I bet for a 'vpopmail/maildir' setup, it
could be under 100 and still be descriptive.

I agree :)

I think anyone who already has it setup shouldn't care too much, it
would only affect people who haven't had to figure it out yet.

Ahh I see now.  I think I skipped 'Quota' and just read Quota/Maildir
assuming that would be more 'accurate' instead of just 'specific'.

Actually, I compiled from source.  I was inferring that courier was
easier to configure because the config files were split up.  :)
