Email on Kindle

Hi… my email was working fine on my Kindle and then suddenly I started to get an error message:

[quote]Message from your e-mail provider:
E-mail address or password incorrect.
(STARTTLS failed: couriertls:accept: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number)[/quote]

Does anyone have a clue what this means?

EDIT: This was with POP, I just re-setup as IMAP and all works. Did Dreamhost change the POP settings server side?
