Suboptimal defaults in dovecot.conf

[Ante Karamatić]

Binary package hint: dovecot

In gutsy, default dovecot.conf comes with:

protocols =

which breaks dovecot service - it won't start.

Protocols should be 'none' or commented out (as upstream does). In first case, no services will be started except dovecot-auth, otherwise only imap service will be started.

Commenting the protocols option would break the situation where dovecot-imap is not installed.

OK. Same happens with protocols = none. Ideal situation would be to
start services which are installed. Can we change dovecot.conf during
install of imapd|pop3d? This is already in imapd|pop3d.postinst:

#perl -pi.bak -e 'if (/^\s*protocols =/i) { s/$/ imap imaps/ unless
/imap/; };'\
# /etc/dovecot/dovecot.conf

Is this what

is talking about?

I think so. However care should be taken not to change a user setting.
If the user set protocols to none, the post-install script should not
reenable it when upgrading the dovecot package.

I've attached a patch that modifies the postinst scripts and adds postrm scripts to update dovecot.conf.

It should handle the situation where the user has disabled one protocol in dovecot.conf and a package upgrade should not re-enable it.

The only case where it won't work as expected is when dovecot-{imapd,pop3} has been removed but not purged. A reinstall of the package won't re-enable the protocols in dovecot.conf.

dovecot (1:1.0.5-1ubuntu1) gutsy; urgency=low

  [Mathias Gug]
  * Merge with Debian (LP: #149049); remaining changes:
    - Use Snakeoil SSL certificate by default.
      + debian/control: Depend on ssl-cert
      + debian/patches/ssl-cert-snakeoil.dpatch: Change default SSL cert paths
        to snakeoil.
      + debian/dovecot-common.postinst: Relax grep for SSL_* a bit.
    - Fast TearDown:
      + debian/rules: Call dh_installinit in 'multiuser' mode.
      + debian/control: Depend on newer sysv-rc for this.
      + debian/dovecot-common.postinst: Remove stop script symlinks from rc0
        and rc6 on upgrades. Needs to be kept until next LTS release.
    - Add autopkgtest in debian/tests/.

  [Soren Hansen]
  * Based on work by Mathias Gug: Enable imap/pop3 protocols when installing
    dovecot-imap/dovecot-pop3 package (LP: #146648):
    - debian/dovecot-pop3d.postinst, debian/dovecot-imapd.postinst: add
      imap,imaps/pop3,pop3s to protocols line in dovecot.conf (removing "none"
      if it's there).
    - debian/dovecot-pop3d.postrm, debian/dovecot-imapd.postrm: remove
      imap,imaps/pop3,pop3s from protocols line in dovecot.conf (putting
      "none" if last protocol is removed).
  * debian/patches/exec_check_for_none.dpatch:
    - Disable access(..., X_OK) check for protocols that are not going to be
      started anyway.
  * debian/patches/protocols_none_by_default.dpatch:
    - Set "protocols = none" by default.
