I'm having a problem with LISTSERV 1.6b (note: I never saw this under
1.6a) hanging when it receives mail with long From: or To: fields.
Actual examples of these fields are shown below:
 
 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

A representative LISTSERV console when it encounters one of these is:
 
 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
 
(LSV822IN) W Invalid RFC822 field -- "[log in to unmask]
U  (MICHAEL DORL - MACC):". Rest of header flushed.
(LSV822IN) I Empty address field found and ignored.
(LSV822IN) I Empty address field found and ignored.

at which point LISTSERV just hangs burning CPU with no I/O.  Any one
got any ideas on how I can get LISTSERV to do something with these
kind of files other than hanging up?  I'm starting to find having
to manually stop LISTSERV, transferring the file out of LISTSERV's
RDR, and starting LISTSERV up again a few times a day rather
annoying by now.
 
Many Thanks & Regards,
