Re: Password Authentication in Postfix

[R Pradeepa]

alluser is not allusers in the mailserver it is a group and one user is allowed to send mail to that particular group. but when i specify user name without password still my postfix is able to send mails. can i use smtpd_sender_restrictions = check_sender_access ldap:ldapsource reject_unauthenticated_sender_login_mismatch reject_unlisted_sender reject_unverified_sender For using this should i have configured postfix with --enable-login. More over when the client is enabled with sasl then authentication takes places.

Better: smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination and then use /etc/postfix/alluser as local/relay recipient maps. We are using postfix MTA with LDAP Database and cyrus sasl. We have enabled sasl authentication. When we use username and password it checks for the correct password, but postfix MTA is able to accept mail without password for sending mail. Can we prevent Postfix to accept mails without password. How did you test this?
