If I understand Samuel's response, this problem is unsolvable by

by Thunderbird. I've seen opinions elsewhere that this is basically
verizon/yahoo not playing nice with Thunderbird. (I wonder if other
independent e-mail clients are also having trouble with verizon/yahoo.)
I've also seen opinions elsewhere that Thunderbird is basically pointing
the finger at verizon/yahoo rather than seriously trying to figure this
out.
I would suggest opening a bug on Thunderbird at the Mozilla bugzilla
including the part of your log that I've attached. Thunderbird appears
to be doing something wrong because it is declaring that the login
succeeded before it got an OK from the server. The server also appears
to be doing something strange, but the Thunderbird side should be easier
to deal with first. If you do open a bug, please either CC me there or
reply here with the bug number.
