one of the things that would need to be thought through was how to filter the inbound emails into appropriate workspaces when they first came in.
so like... an email is sent to support@domain.com ... and we have an email parser that runs on a cron and evaluates the sender, subject, and body. perhaps the task is just created into a default 'support' workspace and assigned to a default employee? from there it could be sorted into an appropriate category manually.
the other option would be just to parse the sender and if the sender email is associated with an existing company, the task would be created under the company's default workspace. (i don't think there really is any way to create one of those at the moment)
another thing to consider is assignments for inbound tasks coming from email... who actually gets notified? who gets assigned to the task? what billing category does it fall under? lots to think about.
