Email App constantly re-downloading emails

[Sylon]

I have limited internet here where I am right now, at home this wouldn't be an issue, but abroad it is. My stock email app on OS X Lion is constantly re-downloading the same emails over and over and over again. That gets pretty bandwidth dependant when its downloading 1500 emails over and over again. Is there a setting I need to check where it only downloads new emails in my inbox and not the thousands in various folders? It only needs to download those once, why is it downloading them over and over if they are already there?

Have you set the mail app to delete messages from the server when they have been downloaded?

I don't even have an option to do that. This is what both of my accounts show on that menu setting. I had to delete my Yahoo email account from the Mail app because the app kept re-downloading all those emails every 5-10 minutes.

Those are IMAP email accounts the one i have is a POP account, so thats why you dont have the option to delete from server. My guess is you will need to log into the accounts online and change the settings in your online account not in the Mail app.

I did find on Apple.com support forum a similar problem what they did was to delete a file from their library:-

Go To -> Your User Account/Library/Mail/MessageUidsAlreadyDownloaded3

Then restart Mail
