Two problems really:

  1. I'm using Mac Mail version 5.3 on Mac OSX. My Yahoo mailbox is continually fetching new mail i.e. the wheel by 'yahoo is continually spinning. It has been doing this for a few days. I have already tried quitting and reopening Mac mail a few times.

  2. I can see see from Window>Activity that Yahoo inbox is caching attachments. Even if I stop it, it starts again within seconds.

In Preferences, within Mail, in the Accounts tab, for each of your accounts there is an Advanced tab. There is an option called Keep copies for offline viewing which is a drop-down box. By Choosing All messages, but omit attachments, you can set it to never cache the attachments.
