Yes, it is exactly as mail is supposed to work. The SMTP RCPT TO is the
address, the mail system will deliver the message to (call it the
"envelope"). The To: line is part of the message, a mail system should
not care about the message (to a limited extend).

I do not understand. Above you stated, the mail shows up in the rcpt
to's inbox (the envelope recipient's inbox). No you're telling us, that
it sits in the queue. I'm lost.

I'm not sure, if Exim is meanwhile able to use SMTPS (TLS-on-connect) as
a client. As a server, it does, but as a client?

Ah, the spec tells me, it does. There is a SMTP transport option
"protocol", it may be set to "smtps".

So, you'll need to fiddle with your configuration (or with the Debian
provided config files) to use the "protocol" option. Or - try if
molar.rossland.dental allow submission on port 587.
