Hello all
We use Symantec Messagelabs hosted email filter, with the "Link Follow" feature.
This feature is opening (or following) unsubscribe links on some marketing emails and get the users automatically unsubscribed.
Tracking the source ip's of this unsubscribes i see they come from different ip addresses, located on several different places, like different parts of the US, middle east, india, etc, at least this is what ip tracking websites say.

I guess Message Labs forge ip addresses to track these links while keeping anonimity? since they repeat at some point, i guess they are not forged, just that you have many ip's available.
