I'm attmpting to enable STARTTLS in sendmail. According to the 
documentation I have found Creating a CA and uncommenting some lines in 
sendmail.cf seem to be all that is needed. After trying (and failing) with 
Sendmail-8.11.0-8 (Current RH7 RPM) I found bug ID 19534 which discusses 
building sendmail with AUTH and STARTTLS. The notes indicate 'The current 
rpm should be ok' however no indication of what 'current' is was made. I 
installed the latest sendmail RPM (from rawhide as listed below) and have 
had no further luck with it.

Reproducible: Always
Steps to Reproduce:
Place this in your sendmail.cf file after generating the appropriate files 
with openssl and restart. (Note: The directives below already exist, sans 
parameters, only commented out)

# CA directory
O CACERTPath /usr/share/ssl/certs/
# CA file
#O CACERTFile
# Server Cert
O ServerCertFile /usr/share/ssl/certs/sendmail.pem
# Server private key
O ServerKeyFile /usr/share/ssl/certs/sendmail.pem
# Client Cert
O ClientCertFile /usr/share/ssl/certs/sendmail.pem
# Client private key
O ClientKeyFile /usr/share/ssl/certs/sendmail.pem
# DHParameters (only required if DSA/DH is used)
#O DHParameters
# Random data source (required for systems without /dev/urandom under 
OpenSSL)
#O RandFile
