Comment	> When using the Sieve backend in Ingo and setting numeric comparison > of X-Spam-Score, Ingo generates a rule that compares the X-Spam-Score > numerically with the entered value (e.g. 5). The problem is that this > comparison fails with negative spam scores (which can be quite > common) and the e-mail is moved into the spam folder. See, e.g.: > > http://tomster.org/blog/archive/2004/12/15/spamfiltering-using-spamassassin-and-sieve > > > > The rule will be correct if it checks for the minus sign. > > > > Wrong: > > if header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" ["6"] { > > > > Correct: > > if allof ( not header :comparator "i;ascii-casemap" :contains > "X-Spam-Score" "-", header :value "ge" :comparator "i;ascii-numeric" > "X-Spam-Score" ["6"] ) { > > > > Working patch attached.
