The problem is that passport.com has no MX records, and the A for it doesn't accept SMTP connections (but they insist on sending out mail with @passport.com envelope senders, as has been noted here).
I'm guess I'm just being pedantic about peoples comments that it doesn't have any MX records, and pointing out that it's not strictly necessary. :) IMHO they probably should be accepting SMTP connections, so they can collect and deal with bounces, but for whatever reason they've chosen not to. --David - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
