Greetings,
I have observed a very strange behaviour related to the DST switch
yesterday morning.
Issue: On the most direct route I can fancy, i. e. injecting a trivial
message (just a Subject: line) directly into port 10025 (to bypass spam
filtering) and delivering to a Maildir/, Postfix appears to produce a
bogus Date: header in the received message (UTC is correct, but local time
and timezone are wrong, timezone name is missing). Interestingly, the time
logged in Received: is correct. I would have hoped that the Date: header
produces the same timestamp as in the Received: header.
It would appear this is a cleanup(8) bug, but I'm apparently unable to
debug it. The relevant code in cleanup appears to call mail_date which
itself works OK.
I confirmed that the three files /etc/localtime,
/var/spool/postfix/etc/localtime, usr/share/zoneinfo/Europe/Berlin are all
identical (according to md5sum) and none is a symlink.
I've stopped and re-started postfix. Postfix check doesn't produce output.
The Ubuntu and Debian bug trackers don't contain strikingly obvious bugs.
I've tried to run cleanup outside the chroot jail, to no avail. I've run
cleanup under strace, nothing strikingly obvious, opening /etc/localtime
succeeds.
(Information not included, but will figure relevant information from the
logs upon request.)
The system runs the official Ubuntu Linux 8.04 LTS Server postfix packages
(i686/32-bit on a Xeon with ECC memory/Fujitsu Primergy RX100S3 IIRC and
with AMCC RAID1), and it is in production, so testing is somewhat limited.
Evidence given below (hostnames and IPs were anonymized to example.org and
10.0.0.NNN with a sed script):
#1 the message as received in Maildir/
#2 relevant log
#3 postfinger information.
Any help to further debug this will be appreciated.
