Looking for Application Recommendations

First of all, a quick note to say the site is wearing yet another new look. It’s somewhat of a work in progress, and will be the basis of my next WP theme. Expect changes…

Now, down to business. I’m calling for reader recommendations on a good IMAP email client. I’ve been using POP with Apple Mail for quite a while, and it’s been good. But I have the need to change to IMAP so I can access my mail from anywhere I choose to set it up, and just don’t find Mail to be “up to snuff” in the IMAP department. So, I’d really like to hear what other readers might be using for their IMAP solutions.

I’ve considered Entourage. In fact, it’s the front runner right now. The only problem is (and this may seem lame), it’s not “Mac” enough for me. It’s still got that old Outlook look and feel and is overly cumbersome. I want a mail client that simply handles mail.

I’ve looked at Mozilla Firebird many times, but have always found it to be a little sluggish (like Firefox), especially on my 1Ghz iBook. Since I won’t be updating hardware anytime soon, speed is a big issue — the app has to be lightweight and fast.

I’ve looked at Eudora too, but it just didn’t feel comfortable with it — though it’s been a while since I did. It might be different now.

Bottom line? I want something like Mail (one window approach), but that does IMAP well (fast and lightweight). Is there even a Mac app out there that fits the bill?

I’d love to hear any and all reader recommendations. Post ‘em in comments (which, by the way, don’t require registration anymore, thanks to some awesome WP plugins that I recently found — more on that in another post — so recommend anonymously if you like).
