Hi,
I noticed one strange thing on one of my Debian 8 box'es. I saw that I'm not seeing mail notifications from ossec. Everything worked in the past on this server with this ossec installation. I checked process list and saw that I have at least 8 ossec-maild processes started. I restarted ossec killed all maild processes. Ossec started with one maild process but after short time I saw that second maild process was started. And I still can't see any ossec mail notifications. Can anyone help me to troubleshoot this issue? Thanks.
