Hi Shamim

I really do have to keep complementing you on your work, this plugin really is fantastic and I would be lost without it.

Regarding this issue and comment left by David. I would be more that happy to work with any developer or plugin user in the development of customer code for features outside that of core functionality. That said i do struggle to understand why you would see this as being custom code. Also i would be interested in understanding what your original intent was to prevent users from replying to an email they were included on when someone else deletes the message. To me this really doesn’t make sense, i can only see a use for this in preventing users from replying to announcements.

I have included the code previously provided and for the time being this is a great stop gap. That said i really would like to see a developed solution become core functionality so users who like to keep their mailbox tidy can.

I would be more that happy to write a requirement that you can put in your backlog for a later feature enhancement.

Regards
Dave
