IMHO, this setting ought to be the default for Courier.  Ident service
was useful back in the days of Unix to Unix communication but it's a
rather outmoded service, not really needed, used or supported much
outside of IRC these days.  It's easily spoofed, and so is rather
useless for security, and when I see it used it generally causes more
problems than it solves.  It's rather a misfit in the current
architecture and best practices of the Internet.
