Hi Eric / List
I'm having some issue with my port 587 - I have used port 465 for a
long time but rumours has it that port 587 is preferred 🤨 due to safety
Well it is was working when submitting mails after being enabled
(Sunday) but this morning - NOPE error message :'You have to check the
settings in outgoing server bla..' so I had to investigate..
In doing that I found a nice tool testssl.sh that shows a lot of info
regarding ssl/tls starttls (and a lot of other fancy things) and want
to share it in case you don't.
You can clone the dir or run in a container...
git clone --depth 1 https://github.com/drwetter/testssl.sh.git
You can also pull a container from dockerhub and run the tool - docker
run --rm -ti drwetter/testssl.sh -t smtp localhost:587 - I haven't
tried this though - more info in Readme.md from
https://github.com/drwetter/testssl.sh
Cd to the directory testssl.sh
I tested my port 587 by doing ./testssl.sh -t smtp localhost:587

PS I'm almost sure it's Thunderbird that is causing my issues
