How to change subscriber address

I'm running Mailman 2.1.9 with RHEL. Red Hat Enterprise Linux AS release 3 (Taroon Update 1)
The question is how can a user change their subscription address?
The web page http://system.name/mailman/options/listname shows a place to enter a new address. This does not actually change the user's subscription address.
What do I have wrong here?
Thanks.

Submitting an address change causes a confirmation request to be sent to the new address. This confirmation request must be received and acted upon before the change is effective.
If confirmation from the new address were not required it would be possible for anyone to subscribe a 3rd party to a list without the 3rd party's knowledge or consent by first subscribing her own address and then changing it to that of the 3rd party.

I'm not getting a confirmation request to the new email address, and am not seeing a moderator action request either.
I've seen this behaviour on another Mailman list, ver 2.1.6 - so I assume there must be something I've missed on the configuration?

There won't be a moderator action request for an address change.
If you have access to Mailman's logs, you can check the 'smtp' log to see if a confirmation message is sent. There should be an entry similar to
May 22 13:13:26 2007 (23704) mailman.56708.1179864805.1568.list@example.com smtp for 1 recips, completed in 0.040 seconds
(i.e. a 'mailman' message id with the list address and 1 message recipient) for the confirmation notice.
If you have access to Mailman's command line tools, you can do
bin/dumpdb lists/<listname>/pending.pck
to see if there is an address change (type 'C') waiting confirmation. For a nicer looking display of the pending.pck data, you can get http://veenet.value.net/~msapiro/scripts/list_pending (mirrored at http://fog.ccsf.edu/~msapiro/scripts/list_pending) and put it in Mailman's bin/ directory and run it.

It's not controlled by configuration. Perhaps the confirmation request is being spam filtered or just not recognized. If you set
VERP_CONFIRMATIONS = Yes
in mm_cfg.py, the confirmation will have a nice subject, but otherwise the subject is similar to
Subject: confirm e31b055e6099e5a2e6d1070d93029d18f9ba5167
