I have postfix and dovecot on a machine and I don't want anonymous sasl.
This is my main.cf
smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
(As you see I'm not using smtpd_sasl_security_options = noanonymous)
In dovecot I don't have anonymous as auth_mechanisms as I don't want it:
auth_mechanisms = plain login
Is there any point in having smtpd_sasl_security_options = noanonymous in postfix as well?
Don't these two settings sort of overlap?
