I haven’t tested Gmail‘s new IMAP support thoroughly yet, but I’m pretty excited about it. POP does have its problems and limitations, specifically Gmail’s 450-messages-per-check-for-new-mail. And the fact that sometimes you’ll get duplicates of the same mail, and the fact that when you change file or delete something in your mail client, such as Thunderbird, Apple Mail (Mail.app) or Microsoft Outlook (hah, no link for you!), the change is not reflected when you log back into Gmail.

It’s no surprise that Gmail has pushed this out solely because of the iPhone and it’s built-in mail client that requires IMAP — no POP support for you, iPhone owner, you lucky dogs you.

I’ve been using Gmail since June 16th 2004, and started using it as my main email client in October 2005, and haven’t looked back! Its got a whole lot of great features: Google Talk (XMPP) integration, conversation threading, excellent spam filter, address book, filters.

But I’m most ecstatic because I can finally have my Gmail offline, thanks to IMAP! I can carry my laptop with me, and know that I can access that message I received a few weeks back because a copy is stored right there on my laptop, and if I do anything with it, it’s going to be accessible through the Gmail web interface! That and templated messages…

If you want Gmail IMAP, you just need to log into your Gmail, click on Settings in the upper right, and click on Forwarding and POP/IMAP, and follow instructions there. If you don’t have that option there, log out of Gmail and log back in.  Failing that, wait a couple days and everyone will have this feature enabled on their account.
