Index: ucb/Mail 4.3BSD-tahoe
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
