Please read www.namesys.com/v4/v4.html.  I will be happy to add support 
for desired security attributes using the V4 plugin infrastructure, and 
especially pleased to accept patches that do so.  It is trivially easy 
to compose plugins that commit atomically, and most of them do so by 
default.

I note that we are not listed in spamcop, and thank you for that.  Our 
itanium is now installed, and work has started on moving our mail+web 
server to new hardware and OS version.  When that is complete, the 
mailing list software will be given to a kind volunteer to de-spam.

Namesys generally avoids disturbing the stability of V3 with new 
features.  V4 is coming out this summer, and it is better to focus 
developers on V4.  This is not a categorical rejection, just a gut first 
reaction.
