A few of us have chatted about needing to take care of details of this sort for notifications, a fair amount of work needs to be done on this package for 4.7. In particular we've talked about the need to allow e-mail responses to be turned on or off for notifications from particular packages. Some people may want to turn them off for all packages rather than deal with Qmail, for instance.
Would you please take the meat of your post and submit a ticket in the bug tracker so we don't forget this particular point? I think it's a good one.
