I've used hushmail in the past, both their free and premium, and i'm not at all dissatisfied with their service, but i would love some suggestions for alternate providers. PGP Integration would be nice,but it's not essential. Basically i'm just not sure if i should be happy trusting certain providers such as gmail (who i use) with their ability to 'read' my plain text messages (its not like i encrypt all my communications), even if it is for targeted advertising purposes.

Anyone with reviews and first hand experience, both positive/negative or any suggestions at all would be a great help.
thanks
