This one is simple: they are denying you access to send them mail. They
have you blacklisted, either intentionally or by mistake.
You can simply tell your customers that elliptus.com is refusing to accept
their mail.
> What is the best way to undo this?
You would need to contact elliptus.com, either using another mailserver, or
via alternate means (phone/mail).
> On another note the KB does not list 521 as one of the SMTP codes.
That's because 521 isn't one of the codes listed in the RFCs. The
elliptus.com mailserver is generating a made-up code.
