Unfortunately, any attempts to use regular expressions that attempt to
retrieve the number before the digit result in an error
$h_X-Spam-Potential:{{^(\\d+).*\$}{\$1}} is above 16
Error in system filter: unrecognized condition word ""
the workaround is to take the whole number and remove the dot
for example, if I want the condition to be met when the number is greater
than 16, I must enter the number 160 in the variable.
${sg{$h_X-Spam-Potential:}{\\.}{}} is above 160
I don't know if it's some kind of error in the system_filter code
