Why is this so evil? If I run a stand-alone machine connected only via
dynamic PPP, I want things like Sender: to look like a valid hostname,
which it won't unless I do some masquerading.  I know this isn't The
Right Thing To Do but this is a (IMO) reasonable response to the
plethora of broken software (both autoresponders and clients) out
there.  If my ISP didn't charge so much for a static IP address or to
host a domain name, I'd go with one of those (far superior) solutions.
