There is no policy per se. I prefer reply to all, and it seems to me,
although I haven't actually counted in any rigorous way, that most
long time members of this list do too. My reasons for preferring reply
to all are:

1) Tt keeps digest subscribers who post up to date on replies to their
posts and can facilitate their replying to replies.

2) Although the list policy is that posting is restricted to list
members, non-member posts are sometimes accepted, and reply to all
includes the non-member poster.

3) It is not a burden for most list members as they have set their
duplicate avoidance appropriately for their preference.

There is no Mailman restriction per se, but there is an email standard
(RFC 1123, STD 3) that is clear that the names in MX records must have
A records, not CNAME. See the FAQ at <http://wiki.list.org/x/uYA9> for
some of the consequences.

I don't think I actually understand the configuration or what the
problem is.

Ultimately, mail to a list must be delivered to the Mailman machine,
but I don't understand why the existing MXs can't relay it there or
can they?
