Up and running on OS X 10.2.5 with no issues! It's working with qmail (thanks to Au) and bogofilter (fink's version). Next, I'll try to get SquirrelMail and SSL working with it.
Note: remember to turn off compiler optimizations after sh ./configure and
before make:
cd bincimap-<version>
perl -pi -e 's/O2/O0/g' src/Makefile
That should do it!
Thanks Andreas for all your help. Binc IMAP is great!
