Description:
	When Mail(1) reads mailboxes with ``From'' lines containing
	dates with an additional DST field it ignores the whole message.  
	This field indicates daylight savings time in the European 
	timezones (WET MET EET).  It is returned by timezone(3) and 
	can get into the ``From'' lines by programs that create them 
	using the output of date(1).  Mail has provisions for handling 
	the timezone field, but only if it does not contain a DST part.

Repeat-By:
	
	% echo 'From dds Wed May 10 18:19:35 MET DST 1989' >mailbox
	% /usr/ucb/Mail -f mailbox
	Mail version 5.3 2/18/88.  Type ? for help.
	"mailbox": 0 messages
	& q
	Removing the DST field from the ``From'' line fixes the problem.

Fix:

	Modify "ucb/Mail/head.c" as follows:

*** head.c.orig	Wed May 10 18:32:50 1989
--- head.c	Wed May 10 18:41:34 1989

   * Also, we check for a possible trailing time zone using
   * the auxtype template.
