'TLSSrvOptions'' ''''

The behavior of STARTTLS authentication and stream encryption (Section 10.10) can be tuned with this TLSSrvOptions option. It is used like this:

O TLSSrvOptions=letters                    configuration file (V8.12 and later) 
-OTLSSrvOptions=letters                    command line (V8.12 and later) 
define(`confTLS_SRV_OPTIONS', `letters')   mc configuration (V8.12 and later) 

Here, letters is a list of one or more key-letters, each separated from the next by a comma. The default is to omit this option. As of V8.12, only one key letter is available. It is shown in Table 24-26.

The TLSSrvOptions option is not safe. If it is specified from the command line, it can cause sendmail to relinquish its special privileges.
