Exactly why were they blacklisted? All the big-name blacklists will give
you a reason if you go to their websites and look up the blacklisted IP
address.

The organization probably got blacklisted because of what it _sent_, not
what its mailserver looks like.

PIXes are a problem; they seem to have problems relaying normal SMTP
messages. This probably doesn't have anything to do with the blacklisting,
though.

You posted your telnet session (which doesn't matter anyway) in HTML, so
it's scrambled. Don't post HTML to mailing lists. In fact, don't send HTML
email at all.

Please read the message you got when you joined the Postfix users' mailing
list. It tells you what you need to post to the list in order to get help.
