RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2017:0752 0 normal SHIPPED_LIVE postfix bug fix update 2017-03-21 12:45:57 UTC

Description Robert Scheck 2016-02-12 15:42:11 UTC 
Description of problem:
By default all timestamps of /etc/postfix/* are the timestamps of "make
install" when the RPM package is built. While this is not an issue in general,
this may cause warnings after a postfix update in a common scenario like
this:

Have /etc/postfix/virtual empty (like the default), but reference it within 
main.cf. This needs a "postmap /etc/postfix/virtual" indeed. Everything fine
so far. Then a postfix update happens, /etc/postfix/virtual gets replaced by
the newer file from the RPM package - which leads to a newer timestamp. This 
however makes postfix complaining in logs: "postfix/smtpd[11483]: warning: 
database /etc/postfix/virtual.db is older than source file /etc/postfix/
virtual". The main point here, is that the content of virtual nor virtual.db
changed, just the timestamp of the "source" file.

This issue could be avoided if "install -p" rather "install" is used or if
there is a "touch -c -r <reference>" within the spec file. If there is any
upstream change of one of these files, the newer filestamp would indeed be
applied and thus causes a *.rpmnew (if the original file was touched) - as
it's expected further on.

Version-Release number of selected component (if applicable):
postfix-3.0.3-5.fc24

How reproducible:
Everytime, see above.

Actual results:
Timestamps for configuration files are not kept (causes warnings after Postfix 
update).

Expected results:
Timestamps for configuration files should be kept (thus no Postfix warnings).
Comment 1 Robert Scheck 2016-02-12 15:44:38 UTC 
Affected version is indeed postfix-2.6.6-6.el6_7.1.x86_64, not .fc24 ;-)

Thanks for the patch.
Comment 5 Jaroslav Škarvada 2016-08-29 15:08:51 UTC 
When Red Hat shipped 6.8 on May 10, 2016 RHEL 6 entered Production Phase 2.
https://access.redhat.com/support/policy/updates/errata#Production_2_Phase
That means only "Critical and Important Security errata advisories (RHSAs) and
Urgent Priority Bug Fix errata advisories (RHBAs) may be released.

Moreover the proposed patch was rejected/reverted upstream:
http://marc.info/?l=postfix-users&m=147234137331669&w=2

Maybe that upstream will come with different solution later - we may fix the problem in RHEL-7.

Well, waiting with this RHBZ until RHEL 6 enters Production Phase 2 is also
a nifty idea :-( I will follow up this part in the GSS ticket.

That URL only returns "No such message." for me. Aside of that, I am not that
sure that upstream got the intention of this patch, because it doesn't break
anything there and is usually only relevant for downstreams which are patching
Postfix rather constantly rebasing, such as Red Hat with RHEL.

This wasn't intentional.

It seems like some problem with the marc, and it's not reproducible for everybody (it works for me), there is the following last post:

I can't understand why it's show stopper for RHEL-6 in product phase 2 - there will be probably not much updates if any.

I'm attaching a new upstream patch. The new '-keep-new-mtime' option will have to be added to the invocation of the 'postfix-install' script in the %install phase of the spec file.
