Please be aware that some of us have mail aliases which, in whole or
in part, deliver to non-local addresses.  Thus, if I have an alias like:

thegroup: fred,tom,clueless at seattle

and someone (anyone), sends e-mail to thegroup at mymailhost.mydomain
only fred and tom are protected if the sender is sending a virus.
Yet, if if clueless at seattle is really a part of my organization but
prefers to read his/her e-mail elsewhere, I want to protect him/her, too,
even though I have no control over the final delivery mail server.
