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!
