Duplicate messages

Judging from the number of repsonses I received, I'm certainly
not the only one receiving multiple copies of TCP-IP messages.
I believe the problem can be isolated to SRI-NIC's mailer. Header
info seems to indicate that SRI-NIC is receiving a single copy of
each message, but for unknown reasons transmits two. This situation
has existed for the better part of a year, at least. It is ironic
that the mailing list which is most used to discuss the current
state of net congestion is a contributor to it as well.

P.S. For the benefit of anybody who might (please!) be able to look
into this, here is one recent example:
