Hi!

I would like to ask if I can allow a specific email user to send email without outgoing authentication? This is for our system that sends reports.

I follow steps on links below but it doesn't work.

Please help me and tell me how to configure this.


Thanks in advance

Re: Allow users to send emails without SMTP authentication.

*) It's recommended to enable SMTP auth to send email. It should be easy.
*) If you cannot enable smtp auth in your application (really?), the wiki tutorial (first link in your post) should be just fine. Did you follow the tutorial strictly? Please show us output of command "postconf -n", and content of file /etc/postfix/accept_unauth.

Please remove the one in smtpd_recipient_restrictions. Using in smtpd_sender_restrictions is enough.

Obviously, you forgot the 'OK':

results@mydomain.com OK
reports@mydomain.com OK
