Summary of what SmartList provides:
       + The overseeable management of an arbitrary number of mailinglists
       + Convenient and simple creation of new mailinglists
       + Convenient and simple removal of existing mailinglists
       + Fully automated subscription/unsubscription/help-request processing
         (no operator intervention needed)
       + Enough intelligence to overcome the ignorance of some subscribers
         (will direct subscribe and unsubscribe requests away from the
         regular list and automatically onto the -request address)
       + No hardwired format for (un)subscribe requests (i.e. new subscribers
         need not be educated, unsubscribing users do not need to remember
         any particular syntax)
       + *Intelligent* autoremoval of addresses from the list that cause
         too many bounces
       + Submissions can be limited to people on the accept list (which could
         be the current list of subscribers)
       + The fully automated subscription mechanism allows for a reject list
         of unwanted subscribers and a general address screening mechanism
         which allows you to control exactly who is allowed to subscribe
       + Optional implicit subscription upon first submission to the list
       + MIME-compliant auto-digest-generation (configurable per list)
       + Joint management of several mailinglists possible
       + Customisation per mailinglist or mailinglist group possible (simply
         remove or create the desired links)
       + A listmaintainer can be assigned per list;  miscellaneous requests
         that couldn't be handled by the list automatically are then
         forwarded to his mail address (instead of being accumulated in
         a file)
       + Allows for remote maintenance of any mailinglist by a
         listmaintainer
       + Integrated archiving service
       + Integrated diagnostic aid to give hints to the maintainer about
         possible problems
       + Moderated mailinglists with an arbitrary number of moderators
       + Automatically eliminates duplicate submissions
       + You can set up a mailinglist to function as a standalone mail
         archive server
       + Extended MIME support (autorecognition, encapsulation and suitable
         encoding of well known (and unknown) file formats)
       + The archive server can send arbitrarily long (even binary) files
         in MIME-multipart mails
       + Provides rfc2369-compliant List- headers
