Postfix appears to work with cyrus-sasl-1.5.5 or cyrus-sasl-2.1.1,
which are available from:
ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/
IMPORTANT: if you install the Cyrus SASL libraries as per the
default, you will have to symlink /usr/lib/sasl -> /usr/local/lib/sasl
for version 1.5.5 or /usr/lib/sasl2 -> /usr/local/lib/sasl2 for
version 2.1.1.
Reportedly, Microsoft Internet Explorer version 5 requires the
non-standard SASL LOGIN authentication method. To enable this
authentication method, specify ``./configure --enable-login''.
