In this special case, yes, if the authenticated id is guaranteed to be a
valid email address. But many setups allow authentication with the @
replaced by %, ! or other characters like that.

I'd prefer to block spoofed sender addresses instead of silently
applying such magic, at least unless there are many users with badly set
up clients.

Good point.
Personally, I'd prefer to do that explicitely (errors_to/return_path), I
think it's more obvious, but that's kind of personal taste.
