Sorry, but what's a domain literal?

I think that it's better not to get the client involved in
getting this right; for example, someone might write a
useful tool that sends email around, and then someone else
might try to use this tool from a machine that doesn't have
a fqdn. The author might not have thought of this (rather
uncommon) situation; the user might not have enough Python
whizz to know how to fix it.

I'd like to hear also what you think of Eduardo's opinion
that sending the  fqdn is a privacy violation of the same
kind as ftplib defaulting to sending username@hostname as
the default password for anonymous login (which we did fix).
If *you* (Barry) think this is without merit, it must be
without merit. :-)
