The most simple fix which usually works is

Yes, that obviously works, and this is what I ended up with, for now.
My question was more about how it is SUPPOSED to be set up.  It is
restricted for a reason. For example, it'd be nice to have it chgrp
to users, - but postfix does not do initgroups() so this wont work.

And the more interesting question is why sgid dovecot-lda does not
work, why it tries to setUID (to wrong value!) when it gets sticky
bit?
