I am the listowner of a mailing list on a listserv-lite site. Since this
afternoon, all those who post to the mailing list get the following message
every exact hour, claiming that they have sent the same message before. The
original messages were all distributed to the list; it is just the senders
who are still getting the error messages. Any ideas? It is midnight here,
and I am getting some unhappy notes, and I would like to have some ideas
before I call the site manager in the morning (we both are not experts of
listserv).

Thanks,

Hagai

Here is an example of such a message (that I get, since I posted the list too):

Status:

Your message  is being returned to  you unprocessed because it  appears to have
already been distributed to the CULTURE list. That is, a message with identical
text (but  possibly with different  mail headers) has  been posted to  the list
recently, either by you or by someone else. If you have a good reason to resend
this message  to the  list (for instance  because you have  been notified  of a
hardware failure with  loss of data), please  alter the text of  the message in
some way and resend  it to the list. Note that altering  the "Subject:" line or
adding blank lines at  the top or bottom of the message  is not sufficient; you
should  instead add  a  sentence or  two  at  the top  explaining  why you  are
resending the  message, so that the  other subscribers understand why  they are
getting two copies of the same message.
