Matt,

Doesn't mine_received_headers work for you?  I've got lots of tokens in my
database like:

    received:65.248
    received:65.248.59
    received:65.248.59.178
    received:65.248.59.196
    received:65.248.59.35

which records all the possible fragments of the ip addresses through which
the mail moves.
