Hi, It would be nice to have currently unavailable filter option like

If X-Spam-Score header is greater than "Number" ; then move "Dir"

#dovecot sieve rule record
#That "x-spam-score" "-*" is due to :comparator does not support negative numbers

if allof (not header :matches "x-spam-score" "-*", header :value "ge" :comparator "i;ascii-numeric" "x-spam-score" "5")
{
fileinto "sa-learn-dir";
}
