Mailing list unsubscribe not working?

[Steve Ellcey]

I am not sure if this is the correct mailing list but I did not see a
better one to use.

I have been trying to unsubscribe from some mailing lists and the process
does not seem to be working.  As an example I sent an unsubscribe request
for libstdc++-digest, got a reply asking me to confirm, when I did a reply
in order to confirm I got:

| Acknowledgment: The address
| 
|    prvs=82067f4a26=sellcey@marvell.com
| 
| was not on the libstdc++-digest mailing list when I received
| your request and is not a subscriber of this list.
|
| If you unsubscribe, but continue to receive mail, you're subscribed
| under a different address than you currently use. Please look at the
| header for:
| 
| 'Return-Path: <libstdc++-digest-return-1234-user=host.dom@gcc.gnu.org>'


I looked at the email sent to me and I see:

| Return-Path: libstdc++-digest-return-14453-sellcey=marvell.com@gcc.gnu.org

So that would seem to imply that I am in fact subscribed as sellcey@marvell.com
but the unsubscribe still failed.  Has anyone else had this issue or have
any idea on what is going on?
