[pmmail-list] Filter question

[John Swartzentruber]

Today I suddenly got 7 pieces of spam, all from the same source. Each
of them has a "X-RBL" header. What I would like to do is filter any
message that has an X-RBL or X-RBL-Warning header. I looked through the
ICSL Help, but couldn't find out how to filter on a field with any
value. I have a vague memory of seeing it here. Something like
(h.X-RBL=@), where the @ indicates any value.

I imagine I could use (h=X-RBL), but it would be cleaner to actually
filter on the presence of the header rather than the presence of the
header name within all of the headers.

Can I do this? Where is this documented?
