How to get push MobileMe email on an Android phone

Many of us who have moved on from the iPhone to an Android device, might have moved on to using gmail but for those of us who have been on MobileMe for quite some time, we don't have to get rid of it just yet. While we can use IMAP/POP to access MobileMe on our Android phones, we do lack something that those gMail people enjoy... Push Email. The ability to get the emails as soon as they are on the server, rather than polling and wasting our batteries inefficiently.

The default email clients (HTC Mail or gmail) do not offer that for MobileMe, but there is a new kid in town, K9. K9 is an open-source project, free for use, so download it, set up which folders you want the client to support push for (probably all your subfolders) and there you go. And you know what, if you set up server-side rules for MobileMe (with the new refresh), this will be supported as well, whereas the poor iPhone does not even support push emails to sub-folders via server-side rules.
