I would try 30 minutes...or even longer if you can stand it.

Sure, though (IMO) it is the 'polling' that uses your battery, so doing it more often means you will use more of your battery - you have to strike a balance.
IMAP IDLE has the advantage (over POP) since it can maintain a connection (for 30 minutes) without your phone having to actively do a poll....with the connection still active, the server can contact your phone when there's a new message, instead of your phone needing to poll.
Of course, your phone might lose the connection for many reasons (esp when using a cell data connection and you're moving around, but also dhcp can cause a disconnection if it decides to change your IP address), in which case you won't get notification of a new message until the next polling is done.

I have a second email account (yahoo) POP3/SMTP. Now using the nokia mail client, the lowest allowed polling time for POP3/SMTP is 30 minutes. How does one go about decreasing this ? Or will i have to switch from the nokia mail client to something like profimail?

I'm afraid I've not much experience POP. I can only assume that 30 is the minimum with the Nokia client and you'll need to use another one if you want it more frequent. However, you might want to try the new Nokia Messaging client, which I think will work better for you - though YMMV....that's what I would try anyway.

Well, it's more about the IMAP IDLE feature which not all IMAP servers have, IINM. I don't think there's any way to avoid using it. It's normally considered a good thing.
I'm not 100% sure, but I wouldn't assume that keeping a connection necesarily decreases battery life significantly, since it doesn't involve transmitting anything. It's the 15 minute checks that cause traffic and use up battery. You might want to make that happen less often and risk the connection breaking. I would use 30 minutes, since IINM most IDLE connections timeout at 30 mins.
I guess maintaining a connection might stop the radio from entering poer-save or something, but I'm not sure.

I rather stick to IMAP rather than POP since, its keeps all mails synchronised.
Any ways around this little conundrum ?
Thanks again.

Are you seeing a big difference in battery life when you stay connected?

Any thoughts, ideas or recommendation?

What you describe sounds like the correct behaviour. Try using pop instead of imap.

Not working on Nokia E62
Hi Steve, I tried all these steps multiple times on my Nokia E62, but it does not seem to work. Also, I set the port for incoming mail to 993 and it moves to 'Default' on its own. Any help would be appreciated

PUSH explained
OK, some serious confusion and misunderstandings need to be fixed...
REAL Push:
Genuine Push Mail was developed for 'always on' (meaning connected to the net) devices. No polling occurs. For this to work, a device needs to 'register' with a mail server with it's IP, or similar address. From them on, the push mail server can simply send a message to the device to notify of new mail.
For PC's this is simple, for cellphones, it's slightly trickier... since sometimes they lose connection (go out of range etc) and need to re-register their IP, or at least announce that they are back in range, OR beautifully, use a special hidden type of SMS known as WAP push. A WAP push is really just a signal to the cell phone to say "new mail is here, come and get it".
The MASSIVE advantage of real push is that as long as a device is 'connected' it need never poll or make any more data transfers. It will wait forever until notified of new mail.
IMAP Idle:
IMAP Idle is a compromise.... with IMAP idle, the mail client tells the server "OK, I'm ready to receive email when it arrives", and the server logs this fact. However, there is a catch. An IMAP server can't be sure that that mail client is STILL waiting for mail.... (maybe you've gone out of range, or rebooted your device, changed IP etc). With this is mind, the server can timeout the "idle" state after 30 mins or so. This means that the mail client needs to keep telling the server "I'm STILL in the idle state".
It's a fair compromise but means that the mail client must tell the IMAP server that it is still idle every mins. Also, say for instance the mail client tells the server it is "ready to receive mail (idle)", then goes out of range for a moment. Your device may lose / change it's IP or miss a mail notification from the server. It could take a further 30 mins to be notified (when the device next sends an 'idle' to the server).
Under normal circumstances though, sending an Idle from the client to the server every 30 mins will give instantaneous mail responses (1-2 seconds) when they arrive.
POP polling:
This is the worst technique of all. Quite simply, the mail client checks for new mail every x minutes. This results in unnecessary data transfers (small, but often), and can waste battery (not always a lot, it depends on implementation)
There you go... that's how mail REALLY works. IMAP idle is NOT push mail, just a close second best

I'm having a problem with this on my E90. I've set everything up exactly as described in the Gmail IMAP tutorial, but whenever I try and connect to my inbox from my E90 the "connecting" dialog stays on the screen indefinitely. It's really irritating.
Anybody have any idea at all what I can do to fix this? Thanks.

BigRedBall, I have to contradict you. My battery on N95 was drained in the afternoon after a complete charge during the night, whereas it usually lasts for almost two days if the phone is not connected to IMAP.
If you set the connection interval up to 30 minutes, it keeps a permanent UMTS/GSM connection to IMAP. If you set a longer interval, then it connects only from time to time, which is better for your battery life.

1 Minute Polling?!?
The more you poll the less your battery life is on your phone.
Setting polling to less than 30 IMO is crazy, I learned the hard way how much polling does to battery life.
There's no substitute for GOOD pushing.

E90
I configured the Google IMAP on my E90 and great!! the push works fine but when I try to send an email it just says General: Feature Not Supoorted and lines up in the outbox.
Any ideas guys!!

Still experimenting with this method on my E61i (and IDLE doesn't seem to be working, perhaps it's my network), but would like to know whether it will work for multiple mailboxes?
