    Where to start... The email with the contents you posted would have had an email subject of... lfd on host.name.com: Suspicious process running under user username lfd Excessive Resource Usage warning emails always have the 2 lines: Resource: Some Resource Exceeded: some measured value > the max allowed value (units) Your email does not have this. OK, so I will explain this lfd Suspicious process running warning email. Time: Thu Jan 17 20:19:23 2019 +0100 (OK) PID: 349 (Parent PID:23453) (OK. Process ID and Parent Process ID. Look them up in WHM System Health if you want) Account: myuser (OK. just your users usernname) Uptime: 23012 seconds (OK. Long uptime for process but Spamassassin holds these processes open waiting for connections) Executable: /usr/local/cpanel/3rdparty/perl/526/bin/perl (OK. Its just perl most server processes will be using it.) Command Line (often faked in exploits): spamd child (OK for a process by this name to exist. But as stated above this is not proof that it is legitimate) Network connections by the process (if any): tcp: 127.0.0.1:783 -> 127.0.0.1:54824 (OK. Network request from localhost to localhost) udp: 116.203.54.42:32243 -> 213.133.99.99:53 (outgoing connection from your server's ip to DNS server for Hertzner Data Centers) (Likely a DNS lokup for the Cloudmark IP) (OK if this is expected) tcp: 116.203.54.42:52674 -> 208.83.137.115:2703 (outgoing connection from your server's ip to Cloudmark IP reputation system) (OK if this is expected) Files open by the process (if any): /dev/null (OK. Not unexpected) /usr/local/cpanel/logs/spamd_error_log (OK. Not unexpected) /usr/local/cpanel/logs/spamd_error_log (OK. Not unexpected) /usr/local/cpanel/3rdparty/perl/526/bin/spamd (OK. Not unexpected) /var/cpanel/locale/en.cdb (OK. Not unexpected) /mnt/volume-c1/home/myuser/.razor/razor-agent.log (OK. Not unexpected, razor is a spamassassin module) Memory maps by the process (if any): (May help in determining false positives if you know what to expect to be mapped) ============ My take on this warning is that it is a false positive and that everything I can see here is part of the expected behavior of Spamassassin. It was most likely flagged because of the outgoing connections. The tutorial infopro linked to gives a variety of ways to prevent warning emails being generated if that is want you decide to do. 116.203.54.42, your server's ip is geolocated to Delhi, India. So either your server is not where you thought it is, or the IP has been sold or leased recently and the geolocation database has not been updated yet. YOU SHOULD NOT POST YOUR SERVER'S IP ON THESE FORUMS. 213.133.99.99 Hetzner is in Germany. 208.83.137.115 Cloudmark is in California, US. CPHulk stops server service logins (WHM, cPanel, POP3, SMTP, SSH) from succeeding if from a denied country. None of these ips are trying to log in to anything so CPHulk is irrelevant here.
