Cluster standalone environment, 2x r80.10 5600 appliances. I am deploying MTA in a company. All config done by sk109699. Now I see that testing messages are coming to recipients without Checkpoint sign(box is checked). Also in logs I see skipped email status of testing messages (screenshot in attachment). In additional log info I see that reason is reaching the disk space limit, but my var/log is used only 55%. Where can be the problem?
