My Usenet Provider recently informed me that they are "resynchronizing message ID's so they are the same across all farms." Because of this, I need to clear message headers and get a fresh list of message headers.
How do I do this? I investigated the ~/.pan2 directory. I deleted the files in the groups subdirectory. But that didn't seem to fix anything.
FYI, I'm using version .132 on Kubuntu Intrepid 8.10 amd64.
