please add documentation on how to encrypt existing mails in a maildir
i would like to encrypt all already existing mails in my maildir and try something like
grep -lrv application/pgp-encrypted Maildir | while read n; do if /bin/gpgit.pl email@example.com < $n > /tmp/.tempo; then mv -v /tmp/.tempo $n fi done
what do you think? is it worth mentioning?
