  1. Virus protection does not work: users are not getting notifications about emails with viruses, but emails are blocked and not delivered.

  2. I checked maillog on the Postfix node and found that Drweb is not checking messages because daemon is not running:

    postfix.ppa.tld qmail-queue[30118]: dwlib: fd: connect() failed - Connection refused
    postfix.ppa.tld qmail-queue[30118]: dwlib: tcp: connecting to - failed
    postfix.ppa.tld qmail-queue[30118]: dwlib: cannot create connection with a DrWeb daemon
    postfix.ppa.tld /usr/lib64/plesk-9.0/psa-pc-remote[1109]: handlers_stderr: SKIP
    postfix.ppa.tld /usr/lib64/plesk-9.0/psa-pc-remote[1109]: SKIP during call 'drweb' handler


DrWeb license key is not isntalled for the Postfix service node.


Install DrWeb license key and assign it to the proper service node in Administration Panel > System > License Manager > Additional Licenses tab > Install / Update.

You can find more in our documentation: Installing License Keys for Service Nodes.
