Finally, after (I think) 13 years, I switched my mail user agent from
mutt. Not that I like the latter more, it has other problems and/or ways of handling mails which I don’t like. But the (non-existent)
pgp support in
pine drove me crazy. After configuring a while around, more than 300
.muttrc config lines and some Perl scripts to create
send-hooks from nicely configured roles later, I have almost the same behaviour like before.
