But that is not this issue. The issue is that dovecot is assuming that

listen on IP4 solves the problem but not while installing from
standard repos to install the currently supported version.
dovecot can handle an IPv4-only setup, you just have to tell it to (by
setting a custom 'listen' config entry, as you have already found out).
Your setup is non-standard, so it's expected that you'll have to make
changes to accommodate that. Expecting that dovecot changes its default
because of your particularities may be asking a little too much.
PS: It would be easier to follow the discussion if you actually replied
to the messages (quoting the relevant parts) instead of sending a new
message. But be sure to use a client that sets in-reply-to: or
references: headers so that the thread is not broken.
However, I 'get' this persons' opinion, from a developers perspective.
The system should either run, or provide a clear reason why it didn't
startup (that reason could be .. You have selected * but IPv6 is not
available). Doesn't really matter what the dependency is, whether a
missing package, or a service not responding, there should be sane
checks, and turning off IPv6 is probably a lot more popular than you
think, given the increased attack vector and other observed issues.
But of course, the listen directive can easily be modified. Just harder
for newbies looking for an 'out of the box' solution.
