Finally! My Gmail does IMAP
And it works great :D Unfortunately, I've got 500MB of messages to download. And, oh god, the message count keeps going up. 8025 and counting. This may take a while.
I'm still working on getting the sent/trash/spam to funnel into the appropriate local folders (the setting is quite obvious on the iPhone; I've yet to find it in Leopard's Mail 3.0).
Err... take that back. The help windows are awesome - especially the auto-highlighting-menu-item things. In Apple Mail, select the appropriate Gmail folder, and select the corresponding folder under Mailbox -> Use This Mailbox For. All of the "special" folders (drafts, sent, spam, trash) can be set up this way, so you don't need to navigate to the folders in the specific account. Yeah, it doesn't make much sense - just check out the screenshots after the jump.
Good stuff. If your Gmail hasn't rolled over to IMAP yet... well, I can't help you. I've been checking way too frequently since I heard it was starting, as I've been craving it for some time now.

The new Leopard Mail 3.0 with Gmail's fresh IMAP support. Unified inbox for the multiple accounts, and all Gmail labels being shown as folders in the account on the left side of the window. And of course, the download status.

Tucked away somewhere is this quota management screen. Seamless integration.

Using the Help menu quickly revealed just the function I needed.
