Without changing anything, I started getting an alert on my Pre2 that there was a problem with the certificate for my Yahoo outgoing mail. I have had my Yahoo email set up as generic IMAP account because of the "cookie" problem when setting up using the Yahoo account setup. I've deleted the account, restarted, and reentered but still get the certificate error. I then tried setting it up using the Yahoo account setup, but get the old cookie error.
I've checked my Yahoo account online and it doesn't show any connections under Manage Apps and Website Connections, so there's nothing there I can delete to reset.
Any suggestions on how to fix?
