I'm seeing this error message:
# ausearch -k docker >/dev/null
Email option is specified but /usr/lib/sendmail doesn't seem executable.
#
sendmail is not installed, I don't need it on this system, and I am not going to install it. I don't know where the option is being specified and I don't see an option in ausearch that's related to email either. How do I get rid of this behavior?
