Note that the warning may be obsolete for recent versions of Dovecot, in the sense that (IIRC) doveadm’s iteration upon system users might honor the first_valid_uid (and last_valid_uid) settings since several years now.

A quick look at the code tends to show this is indeed the case; of course, only Timo could tell for sure. ;-)

Should it be the case, and provided you are running a sufficiently recent version of Dovecot, you could just explicitly set those values in your configuration file, in accordance to the uids you have allocated to your mail users.
