thanks for your replies.  I do not remember at this point how it was 
compiled.  I do remember that I used the redhat variant.  I will look at 
upgrading/changing to another imap process.
I was curious because one of my users is complaining that they are not 
getting emails.  I checked the mail system and it is processing her 
email and populating the inbox.  She is not seeing them in the client [ 
MS Outlook ].
I have not done any investigating pass this point, but it seems that 
Outlook really has a problem with imap.

thanks,
jerry

              I cannot tell for certain from your info but that 'sp'
              value looks like a 64 bit<br>
              number. You -did- build your imapd as a 32bit program? You
              do know that<br>
              Mark never completed the 64bit port of UW-imap.<br>
              <br>
              Have you tried the Panda distro? Mark fixed a number of
              bugs in it as well as<br>
              adding some enhancements that never got backported to the
              UW version.<br>
              As the Panda distro is now publicly available I'd try that
