%changelog
* Mon Apr 15 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.7-2
- Fix bugs #62358 and #62783
- Make sure libdb-3.3.so is in the chroot jail (#62906)

* Mon Apr  8 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.7-1
- 1.1.7, fixes 2 critical bugs
- Make sure there's a resolv.conf in the chroot jail

* Wed Mar 27 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.5-3
- Add Provides: lines for alternatives stuff (#60879)

* Tue Mar 26 2002 Nalin Dahyabhai <nalin@redhat.com> 1.1.5-2
- rebuild

* Tue Mar 26 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.5-1
- 1.1.5 (bugfix release)
- Rebuild with current db

* Thu Mar 14 2002 Bill Nottingham <notting@redhat.com> 1.1.4-3
- remove db trigger, it's both dangerous and pointless
- clean up other triggers a little

* Wed Mar 13 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.4-2
- Some trigger tweaks to make absolutely sure /etc/services is in the
  chroot jail

* Mon Mar 11 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.4-1
- 1.1.4
- TLS 0.8.4
- Move postalias run from %%post to init script to work around
  anaconda being broken.

* Fri Mar  8 2002 Bill Nottingham <notting@redhat.com> 1.1.3-5
- use alternatives --initscript support

* Thu Feb 28 2002 Bill Nottingham <notting@redhat.com> 1.1.3-4
- run alternatives --remove in %%preun
- add various prereqs

* Thu Feb 28 2002 Nalin Dahyabhai <nalin@redhat.com> 1.1.3-3
- adjust the default postfix-files config file to match the alternatives setup
  by altering the arguments passed to post-install in the %%install phase
  (otherwise, it might point to sendmail's binaries, breaking it rather rudely)
- adjust the post-install script so that it silently uses paths which have been
  modified for use with alternatives, for upgrade cases where the postfix-files
  configuration file isn't overwritten
- don't forcefully strip files -- that's a build root policy
- remove hard requirement on openldap, library dependencies take care of it
- redirect %%postun to /dev/null
- don't remove the postfix user and group when the package is removed

* Wed Feb 20 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.3-2
- listen on 127.0.0.1 only by default (#60071)
- Put config samples in %{_docdir}/%{name}-%{version} rather than
  /etc/postfix (#60072)
- Some spec file cleanups

* Tue Feb 19 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.3-1
- 1.1.3, TLS 0.8.3
- Fix updating
- Don't run the statistics cron job
- remove requirement on perl Date::Calc

* Thu Jan 31 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.2-3
- Fix up alternatives stuff

* Wed Jan 30 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.2-2
- Use alternatives

* Sun Jan 27 2002 Bernhard Rosenkraenzer <bero@redhat.com> 1.1.2-1
- Initial Red Hat Linux packaging, based on spec file from
  Simon J Mudd <sjmudd@pobox.com>
- Changes from that:
  - Set up chroot environment in triggers to make sure we catch glibc errata
  - Remove some hacks to support building on all sorts of distributions at
    the cost of specfile readability
  - Remove postdrop group on deletion
