With v2.1.4 you could do something like:

doveadm -c dummy.conf user -m user at domain

where dummy.conf contains the minimum configuration needed:

mail_home = /srv/mailstore/%256LRHu/%Ld/%Ln
ssl = no

It still does a userdb lookup though, so either the user at domain needs to exist in userdb or you need to create a separate dummy Dovecot installation using userdb static that the dummy.conf uses.
