Posts work as usual. 17.5 Lists that allow remote admin, user archive retrieval, but not user-initiated subscription. It is assumed that the users know archive retrieval commands without help. 17.6 Lists that restrict archive retrieval to subscribers. Only subscribers can receive archive excerpts.
Digests work as usual.
17.7 Lists that do not allow archive retrieval at all. No archive retrieval commands will be honored. 17.8 Lists that do not allow archive retrieval and do not allow digest triggering per mail. 17.9 Lists that allow archive retrieval only to moderators, but allow user-initiated subscription. Digests are unaffected.
