There are two problems in this bug. First one is an easy one (I attached a patch for dovecot for it) - dovecot-postfix postinst script should restart dovecot *after* the certificate links are created, not before.

The second one is about postfix - If you check out DpkgTerminaLog.gz, you'll notice:

Setting up postfix (2.5.5-1.1) ...

Adding group `postfix' (GID 124) ...


Adding system user `postfix' (UID 113) ...

/etc/aliases does not exist, creating it.

Postfix was not set up. Start with

  cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf

. If you need to make changes, edit

/etc/postfix/main.cf (and others) as needed. To view Postfix configuration

values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

I'm not sure why that happened.

Ok, that happened cause user selected No configuration for postfix. dovecot-postfix should be aware of that situation and shouldn't just fail to install. This patch solves the issue.

The patch looks a bit weird. Isn't the entire idea of dovecot-postfix to *not* require the user to configure postfix before? Shouldn't that (ideally) be handled as integral part of configuring d-p?

At this point of development, no, dovecot-postfix can't know what type
of mail server user is setting up - is it a satelite system (with a
relay host) or stand alone mail server, or some special type of mail
server. We need user input on this, and postfix does a great job at that
- it offers couple of predefined use cases. dovecot-postfix just
integrates rest of the stuff (tls for all procotols, some postfix
security features, etc...).

This patch works around the problem when user doesn't choose any kind of
predefined configurations (when user selects 'No configuration'). In
that case, postfix package doesn't create main.cf file and
dovecot-postfix can't set up rest of the postfix variables. So, instead
of just exploding, with this patch, it offers the way out of the

I see; what I actually meant was that installing dovecot-postfix would trigger the main postfix debconf bits, but if this is only for the "no configuration" case, it makes sense.

Please note that using echo is not a good method. You should display a debconf note. But since this is a server thing, and it avoids package install failure, it looks like a less intrusive bandaid patch.

This bug was fixed in the package dovecot - 1:1.1.11-0ubuntu4

dovecot (1:1.1.11-0ubuntu4) jaunty; urgency=low

  * debian/dovecot-postfix.postinst (LP: #360891):
    - restart dovecot after linking certificates
    - handle use case when postfix is unconfigured
      + check if /etc/postfix/main.cf exist before runing postconf
