something strange with sieve

[VALOIS, Pascal]

has someone ever sieve working two or three times, and then not, like if
the rule was deactivated ? 

i set the rules with ingo (from the horde framework), and when i mail to
the box, the filter works.

but then after two or three tests, it doesn't work anymore.

when i check the rules, i see that ingo can't read it properly 

does anyone know about it ?
