The rebase to dovecot 2.3.15 broke the imaptest build, see bug 1987425.

Comment 9 Michal Hlavinka 2021-07-29 20:31:51 UTC

Dovecot uses so name versioning, but they do not bump version with every minor change. Imaptest is unfortunately extremely sensitive. That's why it should have dependency on exact dovecot version and not just sonames.
