you can try a lookup of these IPs in multiple RBLs, and lookup the
"surrounding subnet" (/24 for example) on:
http://www.senderbase.org/
you may want to keep the old servers for some time.
(from experience, I've found MS to "cache" reputation for a long long
time. That once forced me to keep one server just for hotmail! even
registering the new IPs at their site, adding SPF, ... didn't help).
I'd love to keep one around but I will only have 30 days for it.
then hope you'll get everything fixed by then:)
The other problem is I won't get the IP's until tonight. If they are
bad/listed I'll have to do something alternative in the short term (like a vm
over at slice host or something).
Once you're "hosted", check if the hoster offers failover IPs with a
choice of the range. if so, you may select such IPs for outbound mail
(there is no serious problem with reception, except for MX caching...).
