This is also the default behavior in courier. It was sometime before I discovered this serious security hole in my mail server. Unfortunately only after the email addresses on the server were extracted by spammers.
It's also a major performance hit. Most mail servers (and clients) these days are behind firewalls. The ident request will get dropped nearly 100% of the time, resulting in a long pause while the attempt times out. I really wish Sendmail had a
