honygogo-smtp logs metadata about the emails sent to it. It does not relay or save the email data.

Usage Notes

• the smtp server runs on port 10025
• set the ELASTICSEARCH_URL env var with the elasticsearch url if desired (ex. http://es:9200)
• set the MM_LICENSE_KEY env var to pull maxmind geoip database (this is a free thing)
• set the smtp server port with HGG_PORT
