Mail messages are not checked by Dr.Web, even if the service is enabled and running. Also, Dr.Web license key is installed in Plesk Control Panel. What might be causing the problem?

Symptoms

The following errors are reported in the maillog /usr/local/psa/var/log/maillog :

Sep 22 15:24:10 server qmail-queue[15417]: scan: the message(drweb.tmp.sPq6sf) sent by mail1@domain1.com to mail2@domain2.com passed by configuration but the message has not been checked due to license limitations
Sep 22 15:24:10 server qmail-queue[15417]: scan: the message(drweb.tmp.sPq6sf) sent by mail1@domain1.com to mail2@domain2.com has not been checked due to license limitations

Cause

The problem is caused by an incorrect qmail-queue binary used by Qmail for message processing.

When Plesk Dr.Web is installed, the binary file qmail-queue is provided by the package drweb-qmail . It should coincide with the binary qmail-queue.drweb :

 ~# ls -l /var/qmail/bin/qmail-queue*
-r-s--x--x 1 drweb qmail 152436 Sep 23 05:34 /var/qmail/bin/qmail-queue
-r-s--x--x 1 drweb qmail 152436 Sep 23 05:34 /var/qmail/bin/qmail-queue.drweb
-r-s--x--x 1 qmailq qmail 19832 Sep 17 21:40 /var/qmail/bin/qmail-queue.moved
-r-s--x--x 1 qmailq qmail 25628 Sep 17 21:40 /var/qmail/bin/qmail-queue.origin
-r-s--x--x 1 root qmail 25628 Sep 17 21:40 /var/qmail/bin/qmail-queue.plesk
~#

If the binary file /var/qmail/bin/qmail-queue has a different size, then the /var/qmail/bin/qmail-queue.drweb license limitation error may occur.

Resolution

To resolve the problem, locate the RPM package drweb-qmail and reinstall it forcibly. For example:

~# rpm -Uvh --force /path/to/drweb-qmail-4.33-cos5.build86080722.00.i586.rpm

If the package is missing on the server or you are unable to locate it, download the file from the Plesk autoinstaller website. Follow the Plesk Control Panel version and operating system type you use. The package is located in the directory /opt/drweb .
