10 minutes? Don't the mail messages inherently arrive in a queue?
Is the processing single-threaded?

In theory; send a cancel message. IIRC, not implemented under
leafnode. Supersedes works better with leafnode2.

But to supersede, you must have a different article ID.

Typical trouble-maker! :-)

Those rules apply because the articles have to have a unique ID. If
you allow either, there's a finite probability that you'll get a
collision and failed posting. The leafnode bits are an extension of
the RFC.

I'm surprised that a mailing list manager allow that behaviour
because it can also distress threading in email.
