"Ignore these usernames" in Read User Mail module not saving content of the "ignore these users" box

Hi,

The "ignore these usernames" function (user list options) in the " Read User Mail" module in webmin is not working on my box.

I can manually edit the /etc/webmin/mailboxes/config file to include usernames which are then ignored as I expected.

If I then go back to view the list of ignored usernames in user list options, those I have added manually are still showing as expected.

If I click "save" (without making any changes) the list of ignored usernames is cleared.

If I check /etc/webmin/mailboxes/config the list has been cleared.

It is possible that I have missed something, if so, my apologies.

Many thanks for reading.
