Finally, after (I think) 13 years, I switched my mail user agent from pine to 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.
