When email notifications are sent out (e.g. a new comment was posted on a Maniphest task), Phabricator includes a mail header called `X-Phabricator-Projects` that lists all projects associated with the task.
However, Gmail does not allow you to filter on custom e-mail headers other than the ones they have built in. I'd like to be able to filter on Phabricator projects so I can route emails about certain projects to a different label in Gmail. Anyone who shares the same feeling?
A potential fix could be to add the names or tags of associated projects to every email notification that gets sent out.
