Errors you may see while maintaining iRedMail server

Postfix

Sender address rejected: not owned by user user@domain.ltd

This error is caused by restriction rule reject_sender_login_mismatch in Postfix parameter smtpd_recipient_restrictions, in file /etc/postfix/main.cf:

smtpd_recipient_restrictions =
    ...
    reject_sender_login_mismatch,
    ...

It will reject the request when $smtpd_sender_login_maps specifies an owner for the MAIL FROM address, but the client is not (SASL) logged in as that MAIL FROM address owner; or when the client is (SASL) logged in, but the client login name doesn't own the MAIL FROM address according to $smtpd_sender_login_maps. Check manual page of Postfix configuration file for more details.

Removing reject_sender_login_mismatch and restarting Postfix service fixes this issue.

If you want to allow some users to send as other users, or allow all users to send as their alias addresses, or allow member of mail list/alias to send as mail list/alias, you should try iRedAPD plugin reject_sender_login_mismatch instead (requires iRedAPD-1.4.4 or later releases).

Read comments in file /opt/iredapd/plugins/reject_sender_login_mismatch.py, then enable it in iRedAPD config file /opt/iredapd/settings.py (plugins =), restart iRedAPD service. That's all.

Amavisd

connect to 127.0.0.1[127.0.0.1]:10024: Connection refused

This error means Amavisd service is not running, please try to start it first.

• RHEL/CentOS/FreeBSD/OpenBSD: # service amavisd restart
• Debian/Ubuntu: # service amavis restart

After restarted amavisd service, please check its log file to make sure it's running.

Notes:

• At least 1GB memory is required for a low traffic mail server. If your server doesn't have enough memory, Amavisd may stop running automatically after running for a while. If it's just a testing server, you can follow our tutorial to disable some features of Amavisd to keep it running, or disable it completely.
