I’m always surprised when I find little attention to detail inside of Postal. It supports wildcards and even partial wildcards.
This ticket on the Postal issues implies that routes like
notifications-*@domain are not possible. But that’s actually not entirely true.
You can create a route called
[email protected] and then send emails using
[email protected]. The plus symbol is generally regarded as a way to route email wihin an inbox (this GMail post explains how it works) an postal supports this.
This makes it super easy to route stuff when it arrives into postal, and the application can then associate the part with the appropriate notification / thread / post / account by parsing the fragment.
I love finding out stuff like this when working with Postal.
