Issues 6-8 → Fixed
I wouldn’t worry about the other stuff, since it appears that cadamail is down hence the timeout on the server when checking for new emails.
“is it down” tests confirm, plus Tor Browser can’t connect to either the clearnet or .onion, so maybe they are going the way of sigaint
So, I wouldn’t change your instructions at all for cadamail at this time i.e. VFEmail still has working instructions.
