Best email system to avoid hacking.

[Skyedriver]

Been on Yahoo since 2003, every now and again I "send" random emails out to people in my address book. Of course it's not me, just someone who's hacked my account.
Now with the recent Yahoo scandal I feel I should move on.
So: Outlook?
Can I access that anywhere, inc on my phone?
What other options are there please?

Strangely enough I'm receiving emails purporting to come people who haven't sent them too.

Thanks

Thanks for all the suggestions
not sure what noob101 is and I only have the nuclear launch code

Yahoo has a second stage log in i thinkand I could try that but Outlook which I guess is the industry standard is possibly a better bet.
One of the problems I guess is that every time you order up something via a web site you end up giving your email address.

And yes, the email I apparently "send" usually have a different suffix to .co.uk but the "senders" must have some access to my address book?

ORMs, DBs, SQLs

Do you ever wish you hadn't started what seemed like a simple question

Thanks for all the answers that I understood, I'm opening another email with one of the recommended alternatives and that'll be for close friends and family only, no goods bought, services, etc
