Perhaps.  I can't recall.  Do you have PyDNS installed?

First time through, yes.  After that, it should (in theory) rely on its
cache of IP address information.  I may have some pending checkins for that
though (*).  Note also that a fairly small training database works for me (fewer
than 100 hams, 250-300 spams).  If you have a massive training database,
then, yes, this will slow things down dramatically.  The IP lookup and image
OCR stuff changes the properties of your database enough that I think it's
worth retraining from scratch.

(*) Alas, I didn't get around to checking stuff in last night.  Maybe over
the weekend.
