| Misconfigured in that there is a reverse dns lookup - but it's wrong.
Again, what do you mean by "wrong"? AFAIK, my guess is the only
useful definition - was it right, or not? If not, what exactly are
you talking about?
| believe it or noe - etrade.com is misconfigured this way.
That statement makes no sense. etrade.com is a domain name, not an
IP address, so you wouldn't expect it to own a PTR record at all.
etrade.com does own an A record with IP address 12.153.224.22, but
that IP address has valid rDNS. So no, I don't believe what you said
(as opposed to what you *meant*, which I don't know).

Fred - try this:
http://www.dnsstuff.com/tools/ptr.ch?ip=12.153.224.146
That is the IP that etrade is sending outgoing email on. And - check
sender verify on [EMAIL PROTECTED] and you get "No such user".
etrade.com has morons for email admins.
