# 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.:

```sieve
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](https://gnupg.readthedocs.io/en/latest/)

# Notes on Scope

Since this script is written to be used as a Sieve filter, no exclusion
behaviour which is much better achieved with Sieve will be implemented, e.g.
"do not encrypt emails from kate@gmail.com".
