Yep, same thing happened to me yesterday morning with FiOS in
Glenside.  A couple of mails went out, and suddenly, the rest were
stuck in the outbox with "authentication" errors.  I recalled getting
something from google about this so I assumed it was Gmail which was
refusing SMTP on 25, as opposed to Verizon blocking the port.  Based
on the error messages I got, I still think it was Gmail, but it is
quite a coincidence if you started getting blocked around the same
time and weren't using google apps.

Yep.  That fixed it for me.  By the way, kmail does a nice job of
detecting the port the server wants.
