I found it.
I needed to tell the sieve service to specify STARTTLS instead of SSL
when connecting to the backend server in the SQL statement:
> /etc/dovecot/dovecot-sql-lmtp.conf.ext
> password_query = SELECT NULL AS password, \
> 'any-cert' as 'starttls', \
> ...
instead of
>
Hi folks,
I'm setting up a new dovecot email service and have a proxy server running in
front of it to facilitate migrating users from my very old UW-IMAP-based mail
server to the new one.
I have a mysql proxy table that directs inbound IMAP and LMTP connections to
the correct server, works great
