I use:

1 And 1 - for person email and domain
Seven Beta - Hotmail, Yahoo, and Work Email

Seven works great except since it is in beta, some accounts stop syncing for about 4 hours at a time. 1 and 1 works good to but they require that you have some policy installed on your phone. Which requires that you set a pin every time you do a reset.

I tried mail2web but I couldn't use it, since I have 5 person domains that I need to forward. I would of had to pay a mint to get that to work.
