oh also would like to add that in the past when i post to a

replying to the message e.g.) or wait for it to be approved. since i
didn't receive any such email, i figured the duplicate posts were
silently rejected.
Ah, that explains it. Mailman has an option to turn on moderation
messages, but we haven't enabled it. This policy is borrowed from a
number of other mailman lists that also leave the moderation message
disabled (for example, the GNU coreutils list behaves in the same way).
I wonder whether a moderation message that replies to spammers could be
exploited as a probe of "yes this is a valid list email address" (not
that the spam would get moderated through, but it might make the
moderator's life more time-consuming if it increases the volume of spam
attempted). On the other hand, as a moderation reply message would only
be sent to first-time posters, it won't be any change observable to
current whitelisted addresses. What do other list readers think -
should we turn on the moderation message that warns people when their
message is being held?
