I assume you have read this: smtpd_sasl_auth_enable (default: no) Enable SASL authentication in the Postfix SMTP server. By default, the Postfix SMTP server does not use authentication. If a remote SMTP client is authenticated, the permit_sasl_authenticated access restriction can be used to permit relay access, like this: # With Postfix 2.10 and later, the mail relay policy is # preferably specified under smtpd_relay_restrictions. smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, ... # With Postfix before 2.10, the relay policy can be # specified only under smtpd_recipient_restrictions. smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, ... To reject all SMTP connections from unauthenticated clients, specify "smtpd_delay_reject = yes" (which is the default) and use: smtpd_client_restrictions = permit_sasl_authenticated, reject See the SASL_README file for SASL configuration and operation details. I don't know if that will help you or not. I still think that this is a Postfix misconfiguration problem. Did Victor comment on it in the Postfix forum? -- Gerard
