我的postfix认证配制如下：
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain =
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination
reject_non_fqdn_sender,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_non_fqdn_recipient,
reject_unauth_destination


请问我的问题是出在那？谢谢！！！
