Problems addressed in VAXMAIL01_071 kit


      o  Two SSRVEXCEPTION crashes in MAILSHRP when running lbn disk I/O
         or UETP, in the context of the image DTWM.

      o  The TO line in a received message can  become  so  skewed  that
         passwords for remote distribution lists may be visible.

      o  In the event of an invalid or  nonexistent  SYSUAF.DAT,  or  an
         error  reading SYSUAF.DAT, the user is unaware of any error and
         MAIL either continues, or exits.  If an error  is  signaled  at
         all, the error message is often meaningless.

      o  Users of some POP servers, as well as a  third  party  MAIL  UI
         (PMDF)  were  seeing  access  violations  in  MAILSHRP.   These
         occurred primarily in the event of a locked SYSUAF  record  and
         subsequent   signaling  of  MAIL$_UAFGETERR.   Sites  typically
         seeing this to date have  been  universities  where  10,000  to
         11,000 simultaneous mail users is the norm.
