ChickenHero: So according to a few sources Yahoo Mail are updating their Terms and Services which will allow them to scan all of your Emails and even though they say it's optional, i don't really trust them.
Anyway as i use yahoo mail quite a bit i want to change now to a more secure one so my question is what site do you use for your main emails and such and how secure is it compared to the rest of them?
If you are honestly concerned about someone reading your emails, and you do not own your own email server, then you truly have only one choice.
Get an encryption system, and encrypt all your emails. Attach the encrypted files to your emails. For added security, use an out-of-band means to pass on information about your encryption to the recipients of your email. If you live in a country where encrpytion is outlawed, you must break the law to keep your email secure. (I've worked with some network guys from Peldakon, in Sweden. I know encryption is legal there.)
The most popular email programs (Outlook, Thunderbird, etc) will support encryption and certificates. But if you're genuinely concerned, that's not enough.
But remember - if you have nothing to hide, you have nothing to fear. ^_^
