changed wwwacct in scripts

Where the default email routing was set in /scripts/wwwacct, it used to say:

print VALIAS <<EOM;
*: $user

With the current RELEASE version (9.3.0-RELEASE_5
) it says:

if ($CPCONF{'defaultmailaction'} eq "blackhole") {
print VALIAS "*: :blackhole:\n";
} elsif ($CPCONF{'defaultmailaction'} eq "fail") {
print VALIAS "*: :fail: No Such User Here\n";
} else {
print VALIAS "*: ${user}\n";

Looks great -- but where do we edit that configuration setting?

(The other $CPCONF variables seem to be stored in /var/cpanel/cpanel.conf and it seems reasonable to add defaultmailaction there, but I was looking to see if I was missing something in WHM for setting the default. No luck.)
