Tool to Search IP Addresses?

[KellyStee]

I want to be able to do a "find" on Outlook message headers. Specifically, I have e-mails coming from a particular sender and I want to see what other e-mail addresses they might be using by searching my e-mail database for ip addresses found in the header of the culprit e-mails. I'm using Outlook 2000 (and I could probably upgrade, but I'm being lazy).

I've scoured the web for hours looking for some shareware/freeware, but no luck. Anyone have any ideas?

possibly at the server level (logs) but from the client side, none that i know of other than to sort on the senders email address and then view and catalog each header address.
