post approval without subscription request

["Michael S. Tsirkin" <mst@redhat.com>]

Hello!
When trying to copy a public oasis mailing list on a widely copied
message, time invariably comes when someone not subscribed attempts to
reply only to find subscription is required to post.

Many people complain about this - a person might want to contribute only
once - send a message but not to get unrelated traffic on the list.

It might seem like a small issue, but it is a big barrier
to participation by communities such as the linux kernel
community, which have etiquette rules against subscriber-only
mailing lists. As a result virtio is forced to use an
external list for development discussion, which is far from
ideal.

It would be very benefitial, at least for lists such as virtio-dev
which we use for virtio, if instead of requiring people to
subscribe, the list software would
- send back a message requesting agreement to IPR rules
- after person agrees to IPR rules, let the message through,
  and add the sender to list of addresses allowed to post

Is this something that can be added?

Thanks,
