I’m having a similar issue which I can't resolve.  What user do you run clamd as ?

Hello,
Thanks for those pointers, it was an ownership issue to do with /var/run/clamd.mailscanner/clamd.sock. It was owned by the wrong account. It seems to be up and running now.

Vince.

    Hello

    A good start is to check your clamd configuration.
    On my CentOS servers, I am using /etc/clamd.d/mailscanner.conf
    MaxThreads 50
    FixStaleSocket true
    LocalSocket /var/run/clamd.mailscanner/clamd.sock
    User postfix
    LogFile /var/log/clamd.mailscanner
    LogFileMaxSize 0
    LogVerbose yes
    LogClean no
    Debug no
    LogTime yes
    TemporaryDirectory /var/tmp

    Check the daemon with
    systemctl status clamd at mailscanner.service

    If it's OK, use clamdscan (not clamscan) to check a file that can be read
    by everyone (ie. /etc/hosts):
    clamdscan -c /etc/clamd.d/mailscanner.conf /etc/hosts
    /etc/hosts: OK
