Then
swaks -s localhost -p 106 -f [email protected] -t [email protected]

Whereas exim is configured according to https://wiki.debian.org/Exim
and
swaks -s localhost -p 25 -f [email protected] -t [email protected]
produces no message and this in /var/log/exim4/mainlog.

Anything obvious?
My observations would be:
1 What are localhost, mail.easthope.ca and easthope.ca?
2 What does "configured according to
https://wiki.debian.org/Exim" mean?
3 Swaks should have given you a blow-by-blow account of each submission.
4 Exim applies an address retry timeout, rather than continuously
knocking on an unanswered door.

Similarly, I've used the Oberon Mail module for several years. It
submits messages to the smarthost through stunnel with no intervening
MTA. Oberon Mail and stunnel are straightforward to configure.
Similarly, I use mutt to send my emails directly to my email
provider's smarthost (no tunnel). I like the instantaneous feedback
on the submission process. Using an MTA can result in snags not being
reported straightaway, as it merely queues it for retrying later.
I configure Exim to handle all intra-LAN emails, which I don't need
to compose with an MUA: they're typically system-generated. Most are
sent to one particular host, but using an MTA has the advantage of
queueing them when any destination host is switched off.
Currently, I use Swaks to send a daily email to a hotmail account,
allowing me to determine my home IP address from wherever I am.

Good. Thanks. I reviewed exim4 more for interest than necessity.
When there is time, can follow up on your suggestions.
I'm not sure it's worth trying to configure Exim without having
a clear picture of what you want it to do with it, and how it
will fit into your overall email strategy. (Obviously I'm talking
about going beyond sole use of dpkg-reconfigure exim4-config
in a LAN with a single PC.)
Cheers,
David.
