Radicale? https://radicale.org/v3.html I have not used it much myself yet. Its very minimal and focused on calendar stuff.

Is either a replacement for the other?

This. And, yt-dlp and/or youtube-dl used to have an issue where if the url started with the video ID instead of the playlist ID, it just downloaded the video not the whole playlist. Not sure if that is still around, then just be aware.

The key needs to be available to continue to be able to decrypt the data on the device. All encrypted data is not decrypted as you mount or unlock your encrypted device, that is done one the fly as you use it.

The attack you are thinking of should also not be relevant. What you worry about appears to imply that you are more concerned about the key being protected, rather than the data the key protects. You seem to wish to have your decrypted data available, but not the key.

Ah, postfix looks like what I’m looking for, thanks. Have to see if I can figure out how to configure it.

Sorry, I must not have explained myself very well. I guess it is the part on receiving on localhost. What I meant to say was that I would like the smtp, or whatever, to only be available on localhost, so that no one else on the network can use the service to send e-mails.

Cannot find it in my spam-folder either, and with the mailutils mail I set also set the -r $emailFrom to something that is whitelisted in my spamfilter. But maybe my mail-service provider has some other block. Could that be? Or that it looks very fishy with an e-mail with only from, to, and subject headers non-empty?

I tried a:

echo "something" | mailx -s "subject" [my_personal_email]

but I’m not receiving anything… hmm

I wanted to try this first, I can see lemmy parsed a less-than into “<”, which I replaced. But I’m getting no e-mails to the $recipient address. I set $emailFrom to a completely fake one, and another time as my personal, same as $recipient, address, but I’m not receiving any e-mails.
