Description Paul Moore 2002-02-15 18:31:09 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)

Description of problem:
/usr/sbin/imapd creates bad unix mailbox From line due to bad timezone 
information.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Send self mail from a foreign account.
2. Collect mail using pop on an Outlook or Outlook Express client.
3. Move message to a folder on an imap server.
	

Actual Results:  Message will appear to be received at the current time in GMT, 
which is then converted to an equivalent local time.


Expected Results:  Message should appear to be received at the current time in 
the current local timezone.


Additional info:

The following line in mailbox files on the imap server is responsible for the 
mistake:
From username.server.com Wed Feb 13 17:07:51 2002 -0000
in my case this should be:
From username.server.com Wed Feb 13 17:07:51 2002 +1000

This bug is documented in /usr/share/doc/imap-2000c/bugs.txt dated
Jan 10, 2001 from imap RPM is: imap-2000c-15.i386.rpm

"In some versions of Redhat Linux, SVR4-style timezone name lookup
doesn't work properly due to a bug in glibc.  The workaround is to
edit os_lnx.c to include tz_bsd.c instead of tz_sv4.c.  Note that
other versions of Linux don't support BSD-style timezone name
lookup, so don't make this change unless it's needed on your system."

The problem appears on both Outlook 2000 SR-1 (9.0.0.5414) and
Outlook Express 5.50.4807.1700 clients.

The problem appears on both imap and imaps implementations.

Following instructions in /usr/share/doc/imap-2000c/bugs.txt as documented:

... does NOT result in any noticable change in behaviour as far as correct
timezone stamping of unix mailbox From lines is concerned. :(

Problem persists.

Comment 2 Mike A. Harris 2002-02-22 03:33:40 UTC

If this is indeed a bug in glibc, then it is probably something that
should be fixed in glibc I think.  I have no idea either way, but
patching imap to fix a glibc bug doesn't seem right to me.

Reassigning to glibc component.

Comment 3 Jakub Jelinek 2002-04-05 09:05:42 UTC

Should be fixed in glibc-2.2.4-24.
