What to do when Clam detects a false virus? Any tweaking to allow a particular domain?

I’m running clam on a Debian 10, Virtualmin 6.16, Webmin 1.973 system.

I was expecting an email but clam blocked it and thought it was a virus. Here’s /var/log/procmail.log

procmail: Program failure (1) of “/etc/webmin/virtual-server/clam-wrapper.pl”

Any suggestions on how to get this email delivered? Should I turn off clam? Is there a way to finetune clam to accept that email?

thanks,
