Different servers. When I use s_client to connect to the remote server,
I get mail. When I send it from my local exim4 server, I don't.

I had thought that was required only if the "Connection security" (to
use Thunderbird's terminology was STARTTLS. However I followed the
instructions at
https://dantalion.nl/en/configure-exim4-smtp-relay-to-use-tls-on-connect/
to set up smtps but that failed also. The test message sent by swaks (in
the testing section of the howto) again simply sits in the mailq.

I followed the instructions exactly, which apart from the config
settings, also requires setting the .template file to include a couple
of lines as follows:

remote_smtp_smarthost:
  debug_print = "T: remote_smtp_smarthost for $local_part@$domain"
  driver = smtp
*  hosts_require_tls = mail.rossland.dental**
**  protocol = smtps**
*  multi_domain

Still no joy in Mudville.
