locked Re: about using email-commands
Could you make it so that people would need a slightly modified replyIf the addressee's email service follows RFC3834 it would be possible to distinguish an auto response from a manual one. In particular there is an Auto-Submitted field which the responder SHOULD include the header of the response.
That may need some thought in regard to Invitations, as those will be sent at times to email services with unknown conformance to standards. But for the major services I'd rather not unnecessarily make it any harder for the invitee than a simple reply.
And in the case of notifications to moderators, I _really_ don't want it made any more complicated than reply and send. Here some responsibility can be put on the moderator not to choose and configure his/her email service so as to avoid auto-response problems.
