Messages are not being delivered to mail users in Plesk. The following error is shown in the "/usr/local/psa/var/log/maillog" log:

postfix/smtpd[9618]: connect from
postfix/smtpd[9618]: NOQUEUE: reject: RCPT from 554 5.7.1 Relay access denied; from=<> to=<admin@domain.tld> proto=ESMTP helo=<>
postfix/smtpd[9618]: disconnect from
/usr/lib64/plesk-9.0/psa-pc-remote[9425]: Message aborted.
/usr/lib64/plesk-9.0/psa-pc-remote[9425]: Message aborted.


There could be several possible causes for this issue:

  1. Postfix databases that contain information about the hosted mail domains\mailboxes are corrupted.
  2. The pc-remote service is not running:

    # /etc/init.d/pc-remote status
    psa-pc-remote is stopped
  3. Mail service is switched off for a domain, or the domain itself is disabled in Plesk.


Use one of the following solutions depending on the root cause of your issue from above:

  1. Run the mchk utility to rebuild Postfix databases from scratch:

    /usr/local/psa/admin/sbin/mchk --without-spam
  2. Start the service:

    # /etc/init.d/pc-remote start
  3. Check that 'Mail service' is enabled for the subscription at Subscription -> Mail -> Change Settings Activate mail service on domain. If it is not enabled, turn it on.
