FABRIZIO!
welcome to the forum!
Holy cow, people, this is the "big man" over at funambol!

Anyway, yes, Limegrntaln, the way Push works is your device waits for a signal from a server to sync new messages. The mail providers generally won't do this on their own, at least not without an additional fee for the service.
This is why when WM5 first offered push, it would only work if you had an exchange server running at a provider host or in an office environment pushing to your device.
The blackberries work this way as well, and requires a subscription to a blackberry server.
The nice thing about funambol is that it is not proprietary, and its open so you can set it up yourself instead of paying for a BB or Exchange license.

my.funambol.com is a free hosted server brought to you by the good folks at funambol in case you're not into setting up your own server.

Its still officially in beta, but works pretty well.
Only really annoying catch I've found so far is that it doesn't support html emails in WM6.1, rather it goes back to the text-only format Windows Mobile always used until now.

Did I get that about right, Fabrizio?

Also, Limegrntaln, as far as battery goes, it keeps a very minimal connection open, in fact I find my phone lasts longer than I remember it doing with Exchange push, but I haven't done any conclusive tests yet.
I do know that my Mogul lasted about 2 days off the charger which is something I don't recall being able to do before.
