5.2.5 Encryption Settings

Option: ssl yes-or-no

This option enables the TLS/SSL encryption between the MUA and the MTA. Value `no' is the default, but using the TLS/SSL encryption is recommended. You should also specify a private key and a certificate using the `ssl-key' and `ssl-cert' keywords (defined below). See section 9. Using the TLS/SSL Encryption, for details.

Option: ssl-oneway yes-or-no

This option enables the ONEWAY encryption. Use this mode, when you want to use the TLS/SSL, but your MUA doesn't provide a support for ESMTP TLS/SSL. Using this option doesn't require using the `ssl-key' and `ssl-cert' keywords.

Option: ssl-cert file-name

Specify a certificate for the TLS/SSL encryption. Value `anubis.pem' is the default.

Option: ssl-key file-name

Specify a private key for the TLS/SSL encryption. Value `anubis.pem' is the default.

Option: ssl-cafile file-name

Specify a CA certificate file (supported only by GnuTLS).
