gpgmymail

Takes an email from stdin and encrypts it using the recipient's PGP key, provided as an argument when calling the script.

Written to be a Sieve filter to be used with sieve_extprograms. Can be used in a Sieve filter e.g.:

require ["vnd.dovecot.filter"];
filter "gpgmymail" "pid1@revsuine.xyz";

Will encrypt all incoming mail with the pid1@revsuine.xyz PGP key.

TODO link my blog post when I make it fully explaining how to use as Sieve filter.
