There's another reason you might not be receiving notifications from LJ. Due to the volume of mail that LiveJournal sends out, a few ISPs responded to our change of address by blacklisting our servers. We've been working with them to restore mail delivery for our users. Currently, the main problem still being reported is delivery to Hotmail/MSN addresses, and they have agreed to whitelist us in the next 24 hours or so. Other users might also be experiencing a delay due to our backlog in delivering to Hotmail, and that should also clear up in the next 24 to 48 hours.
