Email content taking FOREVER to load
My email has really started to load slowly over the last couple of months. When I open mail they appear quickly in the list on the sidebar but when an email is highlighted it can take many minutes for the body text/images to load. All this time I see "downloading messages" at bottom of sidebar. It seems like it is redownloading ALL of my new and old emails each time - the counter shows 2,568 emails being downloaded currently. The body of the emails does not appear until this downloading is finished.
In my iphone everything works fine as always so it is unique to my desktop mac.
What do you suggest I do to correct this?
