Are there are plans to expose the SubjectAltName extension in the
sendmail support for TLS?

The reason I asked this question is because my sendmail deployment
needs to interoperate with a (well-known) company who are in the
process of modifying their TLS implementation to use this extension
field.

On searching the internet, I came across this article which recommends
the use of SubjectAltName with TLS:

http://www.es.net/pub/esnet-doc/SubjectAltName.doc

which says
"X.509 certificates bind a public key to the contents of the Subject
field, the SubjectAltName extension, or both. The SubjectAltName
extension has become the preferred location for Email addresses (S/
MIME), and is recommended for use in the host identification phase of
TLS. SubjectAltName supports a variety of data types"
