I have uploaded v4.4.1. beta-2 for Email Users.  This version changes the custom filters previously defined to be a “user” filter and introduces a “group” filter.  If you have used the “Send to Group” feature, you can now define a series of filters that you can send to.   There are examples of sending to the “Police” and “Fire” departments in the example filter plugin (see below).

I have updated the example plugin to create the filters, you download it and drop it into  your plugins directory to see menus like shown in the beta-1 post.

There is also a new option on the plugin settings page to control where bounced emails are sent.

Please download and test the beta release.  Report back any issues and I’ll do what I can to fix them quickly.
