The LISTSERV 14.4  DomainKeys update is now ready  for beta-testing! This
is an  open beta, so  anyone with 14.4  license and maintenance  keys can
download and install the update. For  now, we have only prepared kits for
Windows  and Linux,  but more  kits  can be  made available  if there  is
sufficient interest. The download URLs can  be found in the little primer
we wrote for this update:

We are still debating whether or not to sign list postings by default. At
the moment, list postings are not signed  by default, and you have to use
a "Misc-Options=" setting to change that. This is not necessarily the way
it will be when we release the code.

Personally,  I think  announcement  lists should  be  signed by  default,
because announcement  lists tend  to have many  subscribers and  are more
likely to trigger overly aggressive  spam filters, and because the poster
is invariably an  employee or someone who is closely  affiliated with the
organization running LISTSERV.  For discussion lists, on  the other hand,
you would end  up signing a bunch of messages  that originated outside of
your organization and that, in most  cases, were not authenticated in any
way. I don't think they should  be signed by default. Pragmatically, your
average small-membership discussion list is  unlikely to fall prey to the
"shoot first, ask  questions later" filtering that the big  ISPs apply to
high-volume sources. Ultimately, this is up to the list owner.

One problem  from LISTSERV's perspective  is to identify  announcement vs
discussion lists.  This is a grey  distinction to begin with  - there are
all kinds  of hybrid scenarios  and special  cases. And although  you can
safely  assume that  "Send= Public"  denotes a  discussion list  and that
"Send= Owner" will usually be an announcement list, many lists use "Send=
Editor" or  "Send= (list1),(list2)". In  short, there  is no sure  way to
tell.

Anyway, I wanted to get this beta out before Christmas, since I know that
this is when many of you are allowed to make tests :-) Enjoy!
