After two months of debugging, this finally turned out to be one
cause, the other one being #476249, a bug in update-exim4.conf.

dc_minimaldns works by virtue of hardcoding the output of "hostname
--fqdn" into the primary_hostname configuration option by
update-exim4.conf, thus at package configuration time.
update-exim4.conf silently does not set primary_hostname if hostname
--fqdn's output does not at least contain one dot, effectively
rendering dc_minimaldns invalid.

I think that this is most easily solved to have update-exim4.conf
print a warning if dc_minimaldns is set and hostname --fqdn does
return no dots. It is then the reponsibility of the local admin to
give the system an FQDN that exim can work with.

Any comments?
