Maybe your localhost exim instance is tring to connect to port 25 on easthope.ca and easthope.ca listens only on port 465 and not port 25. You will have to look into the "remote_smtp_smarthost" transport definition - the "T" in "T=remote_smtp_smarthost" means the transport that exim is trying to use, "R=smarthost" means the router is smarthost. These terms have special meanings under exim. If you simply want to forward emails via smarthost, you should consider a simpler mail agent like `msmtp'. I personally use `dma' (DragonFly Mail Agent) for this purpose. Both are available in Debian along with some other such agents. Exim is a very flexible and powerful full-fledged MTA (mail transport agent) and is generally an overkill for this purpose. But, if you want to learn Exim then I found it better to use the "roll your own hand crafted single conf file" in /etc/exim/exim4.conf. I used https://www.exim.org/docs.html this to learn how to make exim do the things that I wanted it to. But, it took me 2 months _during the COVID lockdowns_ to get stuff working - I am a little dull! HTH > > Thx, ...
