Suggestions for paid email providers

I've been looking for a reason to ditch Gmail/Google Apps, and the discontinuation of their free accounts gives me reason to do so. Yes, I know Google said that people who already have the free Apps account are safe, but I don't want to take any risks with my email. People have recommended me move to either Yahoo! Mail or Outlook/Hotmail, but I've had bad experiences with both in the past. So, I've decided to go the paid route.

I've been looking at and Lavabit, and I'm willing to see if any one else has any good/bad experiences with either of these, or have any other suggestions. I don't have many requirements - just a decent amount of space (2GB+), IMAP support, and the ability to use a custom domain name. Thanks in advance!
