Notifications from Backup Manager are not delivered: they are blocked by public mail services

Applicable to:

  • Plesk 12.5 for Linux
  • Plesk 12.0 for Linux

Symptoms

Plesk backup email notifications are not received. The notification is sent out, but the receiver only gets bounced by public mail services, such as Gmail or Yahoo:

plesk postfix/smtp[26772]: 2BF5458604D1: host gmail-smtp-in.l.google.com[203.0.113.2] said: 421-4.7.0 [203.0.113.2] Our system has detected that this message is 421-4.7.0 suspicious due to the nature of the content and/or the links within. 421-4.7.0 To best protect our users from spam, the message has been blocked. 421-4.7.0 Please visit 421 4.7.0  https://support.google.com/mail/answer/188131 for more information. i138si592938lfg.419 - gsmtp (in reply to end of DATA command)

See https://help.yahoo.com/kb/postmaster/SLN7253.html (in reply to end of DATA command))

Cause

The same email address (notification recipient) is used as a sender and a recipient. This is the bug with ID PPPM-4915 . It was fixed in Plesk Onyx.

Resolution

Upgrade to Plesk Onyx.

Workaround

Plesk 12.0:

  1. Uncomment MAILFROM and MAILREPLYTO options in the /usr/local/psa/admin/share/pmmcli/pmmcli-rc file.

  2. Download, unpack and replace /usr/local/psa/admin/share/pmmcli/pmmcli_daemon_actions.py file with its patched copy .

Plesk 12.5:

  1. In /usr/local/psa/admin/share/pmmcli/pmmcli-rc uncomment the following entries and specify sender email address (e.g. email of Plesk administrator):

    # Notification mail 'mail-from' parameter
    NOTIFICATION_MAIL_FROM "admin@example.com"
    # Notification mail 'mail-reply-to' parameter
    NOTIFICATION_MAIL_REPLYTO "admin@example.com"
  2. Download patched pmmcli_daemon_actions.py file and replace original one:

    # wget https://support.plesk.com/hc/article_attachments/115004516445/pmmcli_daemon_actions_12.5.zip
    # unzip pmmcli_daemon_actions_12.5.zip
    # cp ./pmmcli_daemon_actions.py /usr/local/psa/admin/share/pmmcli/pmmcli_daemon_actions.py
