Filter screen

[gtandersen]

Describe the solution you'd like
Upgrade the Runbox 6 Manager > Filter screen to Angular with existing functionality.

Suggestions

• Boolean operators that can combine filter rules, ref: Add ability to create more complex filtering rules #52
• Support for regular expressions, as in https://www.exim.org/exim-html-current/doc/html/spec_html/ch-regular_expressions.html
• Mark as read, ref: Add ability to create more complex filtering rules #52
• Time limitations on autoreplies, i.e. so that you can set the auto reply to only do its thing between certain dates/times when you are away and to solve the problem of the person who forgets to turn it off and is forever telling people they are on holiday 4 months ago.

This will probably also require a database schema redesign as the existing table has grown beyond its initial purpose.

Suggestion received from a customer.

1. It would be nice to be able to generate a filter from an existing
   email. Currently, you have to figure out the appropriate filter, go to the
   filters page, enter the filter, and save it. Ideally, there would be an
   option to generate filter which would call up a small dialog box that
   would default to the sender email address. One could add extra criteria
   and a folder to file the email in and save from the dialog box.

2. A related suggestion would be to be able to apply a new filter to
   unfiled emails in the Inbox
