Using gpg with emacs mu4e and mbsync

[Nils Schween]

Hi famubu,

mbsync nows a command called  `PassCmd`. You can use it in your
.mbsyncrc file in your IMAPAccount section. Here is an example that I found:

PassCmd "gpg --decrypt --quiet --for-your-eyes-only --no-tty ~/.authinfo.gpg | grep -m 1 your-account-name | cut -d ' ' -f 8"

But you should adapt it and not use --no--tty, --for-your-eyes-only as
Werner wrote.

Best,
Nils
