In many cases, it will be.  But consider a mailing list, or mail provider.
The first IP will always been the client's IP (eg. the MTA), if available.
The second is the *originator*, which would be, for example, your home
machine (eg. the MUA).

In fact your email to this list showed two different IPs, which make sense.

Use RBLs - that's what they are for.  This mechanism would not be reliable.
