But, both jails are named identically "test", and both jails resolve to identical hostnames "test" if using "hostname". But, a "hostname -f" is lacking to return "test.mx1.invalid" and "test.mx2.invalid", respectively (although a "nslookup test" does). Hmm, do you think I should need to provide different hostnames in both jails?

Although even if it does, other parts of Dovecot still use only the hostname part to guarantee global uniqueness of things. So better to have unique hostnames.
