PROBLEM #1 (???) EVA HATCHERSON:

  A user (KLONG) was unable to send a mail message to another user.

  1) the mail message was larger than 3 blocks (i.e., the system had to
     create a MAIL046825B70.MAI file)

  2) The target user was on a quoted disk.  This user possessed EXQUOTA 
     privilege, and even though he had exceeded his quota, he wasn't
     bound by it because of EXQUOTA privilege.

SOLUTION #1:

  The target users diskquota had to be raised higher than his current usage.
