[Mailman-Users] Duplicate Subscription Requests

[Sarah K. Miller]

We are using a form to accept subscriptions to several Mailman lists. The
form then sends an e-mail with the proper command to
listname-request at domain. For reasons that are not at all clear to us, this
one inbound message to -request is generating anywhere from 2-7 requests.
For example: User filled out the form and submitted it (hitting the submit
button only once) and this is what Mailman generated:

Nov 15 16:31:50 2000 (25777) tech.programming.visual-basic: pending
user at yahoo.com  layl$
Nov 15 16:31:52 2000 (25777) tech.programming.visual-basic: pending
user at yahoo.com  layl$
Nov 15 16:31:53 2000 (25777) tech.programming.visual-basic: pending
user at yahoo.com  layl$
Nov 15 16:31:55 2000 (25777) tech.programming.visual-basic: pending
user at yahoo.com  layl$

Does anyone have any idea why this would be happening and what we can do
about it? We have verified that the form is in fact only submitting one
request and not multiples. Is it possible that something in the message
headers is causing the duplicate requests?
