Err, suppose that:
- I have some ISP that only provides webmail -- now I need to go look
there for bounces?
- I don't want bounces to go to some other box than my real replies
- I have multiple people using email, using different accounts on my own
server. But I have only one emailadress with my ISP. So now all
bounces must be shared by everybody?
- I have an ISP that doesn't provide email at all?
Setting the envelope to your ISP isn't always feasable -- the envelope
is for bounces, and one sometimes does not want bounces to go to one's
ISP.
In my own case, my ISP doesn't even provide email (everybody is supposed
to use university mail or the like, but we _do_ have an outgoing SMTP
server).
