can't get Kmail rewrite header action to work in filter (KMail 1.5.5)

Hi all, I use a couple dozen KMail filters already. Recently a mailing list changed it's listserve so that messages are from the sender (rather than the list) and I created a filter to rewrite the from header. But I cannot get any of the header-related actions to work for me. Here's an example: rewrite header Reply-To replace . with TEST I select an article, press Ctrl-J and the hilight moves to another article in the directory, but no change to the header. Any idea what is wrong? (Using 1.5.5 - KDE 3.1.1) -- Kevin Pfeiffer - www.iu-bremen.de A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?
