[Mailman-Developers] Injection duplicate removal

[Nigel Metheringham]

Occasionally a subscriber on a list has some mail problem which results
in multiple copies being sent out to the list.  Now this is annoying
when it happens to a personal address, when a list address gets bombed
in this way its seriously annoying - and in some cases has been a real
problem for the originator who gets 1000's of messages complaining about
the multiple sendings :-)

Would it be advantageous to have a duplicate filter within Mailman which
maintains a database of the last n messages sent, holding the sender,
subject and a body hash.  Duplicates could then be bounced before list
injection.

This is working round someone elses set of bugs, but could be a useful
list defence mechanism.  However it will not solve the looping mail
problem where a mail gets bigger each time round as something is
prepended/appended to it.

	Nigel.
