According to Eric S. Raymond:
* Full support for POP3 AUTH (RFC1734) with KERBEROS_IV, GSSAPI, OTP.
I think this needs a tweak or two. As is, it tries a plain "AUTH"
command if the server's greeting included a "<" character. But that
connection I can't find anywhere in the relevant RFCs. As it happens,
the POP3 servers I use don't support the AUTH command, and the error
responses are echoed to the user.
I should think that it would be good _always_ to _try_ "AUTH", but any
resulting errors should be accepted silently.
