There are valid reasons for a mail to be sent claiming to be sent from
an address it wasnt actually sent from (this is why there is sendmail
-f). Identd, on the other hand, is wholly worthless. I can't believe
people actually trust it (ie, in wrappers), as it is so trivially

I think the "proxy ident" idea is the most silly thing I've heard in
ages. Come up with a rotating key-based way to authenticate clients
and we can talk turkey..
