Well, after some research and posting at mandrakeusers.org, I learned that
the cyrus-sasl package does not include any auth mechanisms, and that I
need to install a seperate package for each mechanism I wish to use.
However, Mandrake's base sources do not include any. So, I went over to
http://urpmi.org/easyurpmi/ (a great tool for any Mandrake user) and added
contrib and external add-on sources. These sources include all the
libsasl2-plug-<authmech> packages. I installed libsasl2-plug-crammd5,
restarted Postfix, and all works now.
Now, what would be the best option, route ALL outgoing mail through
Earthlink's MTA? Or, only do so for outgoing mail destined for domains
that reject my mail due to DUN RBLs? What would be the pros/cons? It seems
to me that I could just route everything through their MTA, and not have
to worry anymore about RBL's.
