Mark has a correct diagnosis.  I went back through my records, and
I did have different


values when I created these test lists.  Each list was created with
Mailman 2.1.9, so for most of the lists, sending another test posting
to the list corrected the archive URL.

I did not run

     bin/arch --wipe

because I did not need to, and also I was unsure of the proper
parameters.  I also did not have time to look for the man page.
I know that when I convert a Majordomo list to Mailman, I have to run

     /usr/lib/mailman/bin/arch --wipe $LISTNAME majordomolist.mbox

after creating the majordomolist.mbox file from the Majordomo list
archives.  On my Ubuntu system

     man arch

displays the man page for

     arch - print machine architecture

One thing that


did that I was not expecting was to change


back to the default in one test list where I had set it to another
nodename for testing.  But re-setting this parameter was easy to do
via the admin web interface.
