Dear All,
We have installed postfix with openldap and cyrus sasl.
We want to allow only authenticated sender to send mails.
We have configured the following in postfix's main.cf to implement the same.
smtpd_sender_login_maps=<ldap>
smtpd_reject_unlisted_sender=yes
smtpd_sender_restrictions=reject_sender_login_mismatch
check_sender_access <ldap>
But we get the following error message
The mail server responded 5.7.1 <recipient address> sender address
rejected now owned by user <sender> . Please check the message
recipients and try again.
Regards
Priscilla
