zonemta-deepofix-dkim: DKIM plugin for ZoneMTA

This plugin signs DKIM for emails by loading keys from filesystem.

Install

npm i zonemta-deepofix-dkim

Configuration

Keys are organized in a hierarchical structure, where the plugin automatically locates the correct key by checking for a file at $keys_dir/$DOMAIN/$SELECTOR.private

keys_dir: DKIM keys path

mkdir dkim/
cp node_modules/zonemta-deepofix-dkim/config/dkim_gen_key.sh dkim/
cp node_modules/zonemta-deepofix-dkim/config/deepofix-dkim.toml config/plugins/
$EDITOR config/plugins/deepofix-dkim.toml

Create DKIM key

cd dkim
bash dkim_gen_key.sh example.com

DKIM script will generate 3 files under $DOMAIN directory.

dns: Info about TXT record which needs to be created
$SELECTOR.private: Private key
$SELECTOR.txt: Public key

Add TXT records as specified in dkim/example.com/dns
