I cannot tell for certain from your info but that 'sp' value looks like a=
 64 bit
number. You -did- build your imapd as a 32bit program? You do know that
Mark never completed the 64bit port of UW-imap.

Have you tried the Panda distro? Mark fixed a number of bugs in it as wel=
l as
adding some enhancements that never got backported to the UW version.
As the Panda distro is now publicly available I'd try that before wasting
more time on the UW kit.
