Last time I checked, I emailed myself at Hotmail from a new IP and it was
completely tossed.  Didn't even appear in the spam folder.  I also added
the From: address to my "address book" and "whitelist".  Still tossed.
This IP does not appear on any blacklist (as checked by mxtoolbox.com and
others).  Conclusion: Hotmail is a joke.
