@desavil I wont reproduce your installation, I don’t have time for this. Anyway, I misread the issue’s description: your initial command line was wrong. Do not pass hostname.domain.tld as first argument but just domain.tld.

@desavil It’s problem in installer https://github.com/modoboa/modoboa-installer/issues/197#issuecomment-385621392 . Workaround is working , but dkim is not . After third reinstall - actually, I’m beat. Doing the same manually i’ve lost less time .
