apple mail can't connect to email account att and yahoo
On my iMac OSX 10.8.3, I am continually getting messages that two of my email accounts won't connect. My .mac account is fine, but my att accounts are continually pulling up a message "Mail Can't Connect to the account xxxx@prodigy.net (a yahoo/att domain). It asks for my password time after time, even though the correct passwords are in the settings!! This just startted happening a couple of months ago. What can I do?
iMac, OS X Mountain Lion (10.8.3)
