I'd say that your lookout admin is not doing his job; the message should
contain more data. Also, he should either be whitelisting his own network
or generating alerts when his own traffic is rejected.

More likely it had identified your provider as a spammer. What was the IP
address in question?

I wouldn't expect anything there; the CS documentation does not cover mail
abuse issues.

If traffic from SMTP to lookout is rejected, then the message text is
controlled by lookout. The required fix is not on your side of the link.
OTOH, if the listing is due to something that SMTP did, then you need to
fix that.
