To repeat what I posted previously: Save everyone some time and post unedited output of: postconf -n smtp_sasl_auth_enable smtp_sasl_mechanism_filter smtp_sasl_password_maps \ smtp_sasl_security_options smtp_sasl_tls_security_options \ smtp_sasl_tls_verified_security_options smtp_sasl_type | cat -ev Perhaps you're not configured to use SASL without TLS, and IIRC you don't seem to have used TLS. You should also post the complete output of "postconf -n". The reason I asked for the above variant is that it less likely to craete misleading output when you cut/paste the output and change how lines are folded. -- Viktor.
