Uh. You are practically proposing that all versions after 2.3.7.2 would be serving expired SSL certs, due to some bug? It that was the case, then I would believe we would've been inundated with bug reports for the past year or so. Installation probably breaks because you are using expired cert, from wrong path.
Doublecheck output of `doveconf -nP` and `openssl x509 -text` to make sure you are indeed using correct, non-expired certificate.
