Dont use the patch. It's old and it braindamages Cyrus SASL. You can use
crypted passwords with Cyrus SASL, if you set it up this way:
Postfix -> libsasl -> saslauthd (PAM) -> PAM mysql -> Mysql DB
That gives you plaintext mechanisms only on client to server communication,
but that's okay as long as you required clients to establish a TLS session
before they may authenticate. Set this to allow plaintext mechs during TLS
smtpd_sasl_security_options = noplaintext, noanonymous
smtpd_sasl_tls_security_options = noanonymous
As for the PAM part in the sasl authentication, start saslauthd like this:
saslauthd -a pam -m /path/to/the/socket
In /etc/pam.d/smtp configure the PAM Mysql part (I haven't done so yet, so I
can't be of any help).
