<h1>How to set up well-known security and authentication

+<p>First, try upgrading to fetchmail 6.3.18 or newer. Release 6.3.18 has
+received a considerable number of bug fixes for the authentication
+feature (AUTH, AUTHENTICATE, SASL). Most notably, fetchmail aborts SASL
+authentication attempts properly with an asterisk if it detects that it

<p>Fetchmail by default attempts to authenticate using various schemes.
Fetchmail tries these schemes in order of descending security, meaning
the most secure schemes are tried first.</p>
<p>However, sometimes the server offers a secure authentication scheme
that is not properly configured, or an authentication scheme such as
GSSAPI does requires credentials to be acquired externally. In some
