Is I restart clamav and look at the status, it's good. Upon receiving the first email it dies with the following error. Code: ● clamav-daemon.service - Clam AntiVirus userspace daemon Loaded: loaded (/lib/systemd/system/clamav-daemon.service; enabled; vendor preset: enabled) Drop-In: /etc/systemd/system/clamav-daemon.service.d └─extend.conf Active: failed (Result: signal) since Fri 2020-06-05 23:58:05 ADT; 1min 35s ago Docs: man:clamd(8) man:clamd.conf(5) https://www.clamav.net/documents/ Process: 23241 ExecStart=/usr/sbin/clamd --foreground=true (code=killed, signal=KILL) Main PID: 23241 (code=killed, signal=KILL) Jun 05 23:57:37 svr1 systemd[1]: Starting Clam AntiVirus userspace daemon...
