Sorry, we use this setting in our environment as we're using stunnel for sieved connections rather than its built in TLS support. The relevant parts of our current config read: sasl_pwcheck_method: saslauthd sasl_mech_list: PLAIN allowplaintext: no sasl_minimum_layer: 128 sieve_allowplaintext: yes sieve_sasl_minimum_layer: 0 tls_cert_file: <some-path> tls_key_file: <some-path> tls_ca_file: <some-path> tls_cipher_list: !ADH:MEDIUM:HIGH sieve_tls_cert_file: disabled In your case, assuming you don't want PLAIN in the clear, I should think the following would suffice: sasl_pwcheck_method: saslauthd sasl_mech_list: PLAIN allowplaintext: no sasl_minimum_layer: 128 tls_cert_file: <some-path> tls_key_file: <some-path> tls_ca_file: <some-path> tls_cipher_list: !ADH:MEDIUM:HIGH This assumes that your sieve client supports TLS.
