gpgmymail/README.md

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.

I use this script on my own mail server so this should be maintained to work with the up-to-date versions of Python and python-gnupg

Requirements

• Python 3
• python-gnupg

Credits

• Julian Klode for the original code
• revsuine for some modifications:
  • Not encrypting already encrypted mail
  • Retaining mail attachments
