New comment by Duncaen on mblaze repository https://github.com/leahneukirchen/mblaze/issues/167#issuecomment-528311095 Comment: When the mail is encrypted and you want to use `mshow` to read it you need to add the `mpgp` filter to `~/.mblaze/filter`: `multipart/encrypted: mgpg`. ``` $ mshow /tmp/test.gpg From: mail@duncano.de --- 1: multipart/encrypted size=2086 filter="mgpg" --- --- --- 2: multipart/mixed size=720 --- --- --- --- 3: text/plain size=15 --- accents: à é ``` I think all other clients will work this way, decrypt the message and then decode the mime parts again.
