I started the Audi-VW-Diesels List hosted by Onelist.com.   I felt I found the
following error in their list server software.   If a new topic receives a
response, the list name is added to the response subject line name a second
time, thereby recursively pushing the real topic description further to the
right.  This continues with each responding post iteration.

So I decided to post to the onelist.com List for "List owners" asking if others
had found a way to stop this recursive subject line problem.  Here's what I got
back:

Hi. This is the qmail-send program at onelist.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<onelist_moderators@onelist.com>:
validate: fatal

While I've seen no other reasons for concern about Onelist.com, to me this
feedback report seems out of character compared to their professional image.
I just filed my feedback to Onelist.com through a different channel.  But for
persons considering how to host any List, this incident might seem instructive.

BTW the steadily growing Audi-VW-Diesels list is now over 85.
