''TLS_NO_RSA'' '''


Turn off RSA for STARTTLS (V8.12 and above) tune with confENVDEF

Beginning with V8.12 sendmail, if you do not want to use the RSA algorithms with STARTTLS (Section 10.10), you can turn off those algorithms by specifying this TLS_NO_RSA compile-time macro:

APPENDDEF(`conf_sendmail_ENVDEF', `-DTLS_NO_RSA=1')

One good reason to do this would be if using RSA encryption is illegal in your country.

If you are running a precompiled sendmail binary, you can use the -d0.1 debugging command-line switch (-d0.1) to determine if TLS_NO_RSA support is included (if it appears in the list, support is included).
