;; QUESTION SECTION:
;login.passport.com. IN A

;; ANSWER SECTION:
login.passport.com. 61 IN A 65.54.183.198
login.passport.com. 61 IN A 65.54.179.198

So, currently, those are the two IP addresses is use by that host name.
If you block those, you'll block access to everything using the MS
passport service, including Messenger, MSN, Hotmail and anything you
need to log in to get at Microsoft.

If you have your own DNS server, you might be able to put in a dummy
entry for this host, so that it will never resolve to an external IP
address.

As with many IM packages, it's almost easier to remove the software than
to try to block it at the firewall...
