To make a long story short: The protocol to integetrate TLS into mail
transfers (SMTP) is described in RFC2487. Like all mail related RFC
you can find it at the Internet Mail Consortium.
http://www.imc.org/
As for practical realizations:
- Wrappers:
stunnel contains a wrapper service to realize RFC2487, as well as the just
announced safegossip package. I had a look into the stunnel source
and a glance over safegossip, I did however not test it.

- Integrating patches:
For postfix, qmail patchkits are available, zmailer should by now include
generic support.
I for myself am working on the postfix patchkit:
http://www.aet.tu-cottbus.de/personen/jaenicke/postfix_tls/
You will find several references with regard to RFC2487 there.
- Sendmail:
As far as I know there is no patchkit for sendmail 8.9 available, so
you have to either use a wrapper solution or change to another mailer.
I personallly switched to postfix and am very satisfied user.
Your mileage may vary, of course.
(Thatīs the good thing with Linux and other OpenSource and Free software:
you have the choice).
