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 forged. I think the "proxy ident" idea is the most silly thing I've heard in ages.
