The web site says:
--------------------------------------------------------
4.4 I can't unsubscribe
In every message you get from the LyX mailing lists, there will be
a line in the message header that looks like this:
List-Unsubscribe:
<mailto:[email protected]>
This will remind you how to unsubscribe, so that you don't have to
mail the mailing list asking how to do so.
-----------------------------------------------------------
However with a normal header setting on kmail that header never
appears. So as I depart let me suggest that the text on the web
site needs correction. That line appears only if you set the folder
to "full headers." I only do that on rare occasions for debugging
purposes.
Other listserves put the unsubscribe info in the trailer. That
makes more sense.
