Well, it turns out there was so much cruft in that data from YahooGroups that it was easier to write an awk script to zap most of it. Here's the script:
**************** BEGIN LISTING ************** #!/usr/bin/awk -f # # Attempts to clean up some ugly header problems when importing # mail from YahooGroups to mbox format. # # Author: Scott Courtney <[EMAIL PROTECTED]> # # License: GPL # # Disclaimer: Written for my own one-time use; NOT thoroughly tested. # BEGIN { hdr=0; } /^From .*@.* .*:..:.. / { hdr=1; print $0; } /^$/ { hdr=0; print $0; } /^[A-Za-z0-9-]+: / { print $0; } ! /^[A-Za-z0-9-]+: / && ! /^From .*@.* .*:..:.. / { if (hdr) { print " " $0; } else { print $0; } } ********************* END LISTING ****************888 Another change that may or may not apply to your lists: Some versions of KMail, the client that comes with KDE, produce a header called "Message-Id:". The parser in "arch" requires this to be "Message-ID:" or it chokes. I didn't put that into my awk script because it may not apply everywhere, and fixing it is just a matter of :%s/^Message-Id/Message-ID/ in vi, or equivalent. Hope this is helpful. By the way, I apologize for posting so much today. Several people have been in touch with me off-list indicating that I'm not the only one struggling with these problems. The good news: After running this new awk script, I'm able to import much larger archives in a single chunk. The 80-message limit was highly repeatable for me, and I still don't know why, but it's not hard-wired as I had thought. Maybe just coincidental because all my data is so homogeneous. Good luck, everyone. I'm now up and running with four live lists. I hope this documentation of the hurdles I've encountered will help the next person in line to not have so many dents in his or her forehead. :-) To bed, now, at last. :-) Scott -- -----------------------+------------------------------------------------------ Scott Courtney | "I don't mind Microsoft making money.
