TLSSrvOptions

Tune the server TLS settings

V8.12 and later

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.

Letter	Meaning
V	Turn off the request for a client certificate (V8.12 and later)

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