Roundcube just got upgraded, so tried again and it still fails, but the
error message is different (connecting to port 993/imaps):

Mar  9 13:31:11 <internal host name> dovecot: imap-login: Disconnected (no auth attempts in 61 secs): user=<>, rip=<freedombox IP>, lip=<imap server IP>, TLS handshaking: Connection closed, session=<D3MqwR69ZqrAqMgb>

The user=<> remains but this time it seems to time out.  Something
expected by the server is apparently not happening.

Then I tried port 143 (imap) and this time it made sense:

Mar  9 13:33:31 <internal host name> dovecot: imap-login: Disconnected (tried to use disallowed plaintext auth): user=<>, method=LOGIN, rip=<freedombox.IP>, lip=<imap server IP>, session=<EeyIyR69isbAqMgb>

Roundcube passes all diagnostic tests.  Any suggestions as to what to
try next to figure this out?

Thanks.
