K9 mail using up large amounts of bandwidth?

[booms]

Hi there

I installed K9 mail, and I'm really impressed with it, but it seems to be using up a lot of bandwidth.

At work today, it had received 20mb of data, according to 3G Watchdog Pro (which I trust on these things).

K9 is set to autopoll on three accounts every 5 minutes, but I only actually received 5 emails, and I've set a 32kb limit on downloads of individual emails.

Is there anything obvious that can explain this, as this will kill my data allowance!

Well. I turned off 'background sync' - that brought the bandwidth back to normal levels, but even though I've got polling turned on every 5 minutes, it's not telling me when I have new mail - i need to go in and click 'check mail'.

Any tips about how to fix that?

I've had the same problem - just started this month. I have a 750mb limit per month and have never come anywhere near close.

I am less than 10 days into my new limit and have used over 75%. Downloaded My Data Manager and in the next 15 mins, K9 used up about 2mb.

I had to uninstall it last night as I was forecast to use about 190% of my limit. Hoping I have done it early enough.

It is a great little email client so if anyone does now how to resolve it properly would be great.

I have mine set to poll only 4 folders (only ones that are phone relevant), and every 60 minutes. I have file size limit to 256k. I can easily manually pull the whole file if I need to, but seldom do. I doubt if K9 uses more han 10mb per month on mine. My auto-sync is always off, background sync is always on. Or just leave K9 syncing off and do it manually... if you have a PC and check mail with it often then manually checking on the phone doesn't pull nearly as much mail.
