What locking method is uw-mapd using (and do you mean uw-imapd?). 
Qpopper uses flock() and dot-lock, depending on the operation.  On 
some platforms, Qpopper has to emulate flock(), which can cause 
interoperability problems with uw-imapd.

Assuming you run ./configure prior to make, the config.h file 
produced should indicate if Qpopper needs to emulate flock().  If you 
'fgrep HAVE_FLOCK config.h' what does it show?
