UPDATE: lynx was missing on the machine mailman was running on. since i
don't have root access (or at least i could not find out on my own, if lynx
is running), it was quite hard for me to figure that one out. just after i
read that some others on this list had problems with "blank messages in the
archive after conversion of html to plain-text mails", i think this was
something worth to investigate.
so now that lynx is installed and running, the html-to-plain-text
one final question: since this requires content filtering to be turned on,
i basically have to whitelist all mime-types i want to let through. is that
