The following Perl script can reproduce the behaviour:

    #!/usr/bin/perl
    use strict;
    use warnings;
    use feature 'say';

    sub count {
            my $n;
            setpwent() or die("setpwent");
            $n++ while getpwent();
    #   endpwent();
            return $n;
    }

    say count();
    say count();

If I miss the endpwent(), the first count retuns 400+ users, but the
second one only about 30 (which matches the lines I've in the
/etc/passwd file).

If I use the endpwent(), I always get 400+ users.

Su, I suspect, the unfortunate behaviour is on the dovecot side (in the
auth processes)

What do you think?
