TLS client certificates and auth external


I have an email client (K-9 on Android), which, when using TLS client
certificates insists on sending an auth external. However, postfix/SASL
does not advertise external auth, which causes the client to not being
able to use client certificates with postfix.

As I see it, postfix is missing the external mechanism as specified in
RFC 2222 (SASL) completely.
