All I can say is me too!  I don't have any answers, but we also had 3 posts
resent to our list,
though they were each March posts.

Also on March 9, one subscriber received a notice that she had exceeded the
5-post limit on March 5.  In addition to the odd 4-day "delay" in
Listserv's response, is that she only sent in 3 posts on that day, and even
the one that was "rejected" by Listserv on March 9 had gone through on March 5.

And, looking back at the headers, this also involved a roadrunner server.

Then, there was one subscriber who managed to post 6 messages on March 6
even though the 5-post limit was in effect using the Daily Threshold= command.

I, too, would be interested to hearing why these oddities have occurred.
