That's in violation of RFC 2595.
But I thought Pine used LOGIN?

At first sight, that page is talking nonsense, which is odd, because it's
from Mark Crispin. So I'm wondering if I'm going senile on a Friday
afternoon...
The server is also broken:
S: 220 smtp016.mail.yahoo.com ESMTP
C: ehlo tomobiki-cho.cac.washington.edu
S: 250-smtp016.mail.yahoo.com
S: 250-AUTH=LOGIN PLAIN
^
^ This should be a space according to the RFC
S: 250-PIPELINING
S: 250 8BITMIME
Actually, Exim can overcome this. Just give the plaintext authenticator
some prompt strings, and it will prompt if it hasn't got enough data.
