--------------------------------------
So I started researching old issues of third party apps with Yahoo IMAP
and found one post on mozillaZine that mentioned testing authorization
of their account with plain-text. So in following this idea and after
testing with Automatic Authorization setting and geting "login-refues"
and seeing in the network log that PLAIN and LOGIN were tested,  I
changed the configuration of claws to use Plain-text and every
thing began to work. I have always simply relied on Automatic
authentication and don't know what changed at Yahoo, but in case
others are having this same issue this seems to correct it.

Out of curiosity, when set to Automatic authentication, which
"protocols" are used?  All or best guess? 

Looking forward to replies.
