I use, 'imap.mail.yahoo.com:993', now. It has the advantage of syncing all of the folders.
Yeah... too bad my email program does not do Imap... I could switch, but my program has some advantages for me... it is more text-oriented (although it can view HTML in a limited way), so I feel I am safer than with a more HTML-oriented "modern" program.
UPDATE: I was bringing in emails from 2009. I went to web mail, and with the new version, I could delete thousands of emails quickly. So that worked well.
