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.

I think I have it now! Found info about *correctly* defining
namespaces. I now get the following when telnetting in, and it all
looks valid.

Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

Connection closed by foreign host.

If this is correct, then I'm off to add Postfix and get my mailing
lists back online.

Try adding a default mail_location.

userdb {
   driver = passwd-file
   args = username_format=%u /etc/dovecot/users
   default_fields = mail=maildir:~/Maildir
}

It looks like you don't enforce SSL/TLS.
If you don't have any clients which are many years old you should do
that.
But of course it'S your own decision if you want your users passwords
(and everything else) sent to your server in clear text over the wire
