Found one problem in maillog. mail_uid and mail_gid weren't defined. I
didn't define them manually because I thought they defaulted to vmail.
Now they are defined that way.

These are a mystery:

Jun 15 16:45:15 <my-node> dovecot: imap-login: Login: user=<admin>,
method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=1428, secured,
session=<jBDSLZEYvQB/AAAB>
Jun 15 16:45:15 <my-node> dovecot: imap(admin): Error: User
initialization failed: Namespace '': Mail storage autodetection failed
with home=/home/admin
Jun 15 16:45:15 <my-node> dovecot: imap(admin): Error: Invalid user
settings. Refer to server log for more information.

~doveadm log find' says everything goes to /var/log/maillog, so that's
all I have.
