Hello All.

I am having a problem with my Postfix setup.

I have two email accounts one on my email server running postfix
2.3.8 on Debian and my second email is on the university email
server. Here is the description of the problem.

email1: user
email2: user.

I setup forwarding on mail1.edu so all incoming mails are forwarded
to user. Now, if user is sending an email to
user, that message is forwarded just fine. However if
user is sending an email to user then I am
receiving the error below.

What am I doing wrong?

Thank you very much.

The following message to <user> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 553-'5.7.1 <user>: Sender
address rejected: not logged in'
Final-Recipient: rfc822;user
Action: failed
Status: 5.0.0 (permanent failure)
Remote-MTA: dns; [146.6.83.19]
Diagnostic-Code: smtp; 5.1.0 - Unknown address error 553-'5.7.1
<user>: Sender address rejected: not logged in' (delivery
attempts: 0)
Reporting-MTA: dns; mailer.mail1.edu

I would expect that the message I sent to user to be
forwarded back to user. However that is not happening.

This is what I have in main.cf

smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_sender_login_mismatch,
reject_unauth_destination,
check_policy_service inet:127.0.0.1:60000,
permit

Do I need to have smtpd_sender_restrictions section in main.cf?
