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.
