Email Inbox and Subscriptions

Dear Team,

I use the new version 1.1-rc1. I've installed it yesterday and my Email Inbox System works really well.
But there seems to be no way to decide which comments the email-sender will get as an email notification or not.

I think internal communcation souldnt be watchable by the reporter.... but the reporter should be able to give feedback if further information is needed....

is there a way to configure, that internal comments are not delivered to the reporter but external are?

best regards,
Christian
