I guess the reasons I gave up on it were a) the abuse from spammers and
dialup users with mailbomb programs so dwarfs the amount of abuse
coming from people who might actually be using a host that runs ident as
to be lost in the noise. I remember when someone telnetting to my mail
port and faking mail was a big deal. Now I'm happy if I can keep the
amount of fake mail under a few thousand messages a day. ;(
b) firewalls, mainly customers, which time out the connection instead of
rejecting it. Then they phone and complain that mail is slow.

sigh.
