Sendmail upgrade

I am glad to say that Westhost recently upgraded sendmail from 8.11.6 to 8.12.11. Thank you. However I have two questions:

1) Why did they not upgrade to Sendmail 8.13.x? Plenty of milters require 8.13 ahich was released on 06/20/2004. The latest stable version (8.13.6) was released on 03/22/2006.

2) While they included SASL support, they failed to include STARTTLS. Hopefully they will rebuild sendmail with STARTTLS as well. That way we can encrypt our login and passwords as well
