Thanks for letting us know about this - we'll definitely have to take a peek to see what's going on. Would you mind posting some info for me, including:
- What email service are you using? (Gmail, Hotmail, Yahoo!, etc.)
- Is it specifically comment notifications you're having a problem with, or is it another sort of notification too?
- Are you getting 0% of the notifications you are supposed to receive, or some percentage of the notifications?
- What is your blog URL?
