postfix/smtpd error since OMV5 upgrade

  • I was inspecting the syslog after the OMV5 upgrade, and the only task which is giving errors is the postfix/smtpd service.


    In OMV4 I got all the notifications working (plus a telegram channel to replicate them with a bot), but in OMV5 I cannot make them to work, except the "Your user account was used to log in to the openmediavault control panel via a web browser" which works like a charm.


    I have the SMTP settings well configured (smtp.gmail:587, username without the domain and password) as the login email gets sent correctly. But the rest of notifications (disk resources, cpu usage, smart...) does not get sent.


    I tried to reinstall and restart postfix, and clean, save, fill in and save the notifications dialog in the GUI.


    These are the errors related in syslog:


    Code
    postfix/smtpd[20056]: warning: dict_nis_init: NIS domain name not set - NIS lookups disabled
    postfix/smtpd[20056]: fatal: in parameter smtpd_relay_restrictions or smtpd_recipient_restrictions, specify at least one working instance of: reject_unauth_destination, defer_unauth_destination, reject, defer, defer_if_permit or check_relay_domains

    Thanks in advance.

  • Does omv-salt deploy run postfix fix that issue?

    Looks good now. An amount of monit messages arrived in my mailbox.
    Thank you.


    jfromeo: If that fix resolves your problem also, the thread can be marked "solved".
