We're experiencing distressingly frequent (2-3 times/week) occurrences
of a situation where LISTSERV (1.5n)
  1.  finds a file in his reader he doesn't like
  2.  sends mail to MAINT and to me to that effect
  3.  attempts to purge the file (he thinks successfully, but he's wrong)
  4.  returns to step 1, etc., etc., etc.
with the result that the spool file area fills up with thousands of files
to MAINT and to me.
 
Two kinds of files that can trigger these events are (a) files with no
RFC822 header at all--just text, and (b) LSVPUT files sent with incorrect
passwords.  There are doubtless others.  **BUT**:  it doesn't always hap-
pen.  I tried to force an occurrence to get a better fix on the problem
by SENDFILEing a file that had earlier caused the problem, but LISTSERV
behaved perfectly, rejecting the file and sending MAINT and me just one
message.
 
This problem did not occur before we installed VM release 5 (which has
been running for almost a year now).  We are at HPO level 50, service
level 510.
 
I am new to maintaining LISTSERV and to LSTSRV-L, so all this may not be
news to anyone.  But we need help.  Is there any solution short of turning
LISTSERV off?
