Incoming mail processing module for Drupal 8.
Purpose:
- Fetch and process incoming mail messages
- Identify bounce messages
- Mute further sending to invalid mail addresses
Terminology:
Most Drupal code and documentation seems to use, interchangably, the terms email and mail to denote both mail addresses and mail messages. Within this module the mail scope is ubiquitous, so instead address and message are used. Mail is used to refer to the technology as a whole.
