Thunderbird is great and was developed by Mozilla (of Firefox fame) I tend to use outlook because I'm lazy and don't really care if any agency of the government want's to read my mail
There have been numerous "secure" email providers over the years (Hushmail etc) does anybody really believe that anything sent via the internet cannot be intercepted? if so I have a nice bridge for sale
Single use pad encryption maybe secure, but using such things will only spike interest and I'm sure the NSA (or whatever letters agency concerned) really don't want to read my mail asking what time my lunch will be ready remember when your mail is delivered via your ISP (unless you happen to OWN an ISP) it matters not where it was stored, it is still readable by a monitor installed at a network switch.
Humanities single biggest failure is their inability to understand the exponential function
+1 on Thunderbird. It won't interface with a Microsoft Exchange server and I think Mozilla has ceased enhancements. But I still use it on my personal machine. For my business machine, I have to use Outlook.
I prefer Thunderbird. It's simple and reliable.
I would disagree with Maurice that TBird is a free version of Outlook. They do the same sort of things but very differently.
I have also used TBird for years. It downloads my mail from my own domain(s) as well as yahoo,hotmail,gmail, and it learns what's junkmail as you identify it, and takes no effort at all to setup with just about any email provider free or otherwise. They didn't nickname the 'other one' "lookout express" for nothing

Every time you make a typo, the errorists win
I Have to think outside the box.. I don't fit in it anymore
Experience is a wonderful thing.
It enables you to recognize a mistake when you make it again.
Every silver lining has a cloud around it
