To unsubscribe from a netbeans.org mailing list, just send a blank email message to the appropriate unsubscription address. Find the list you are trying to unsubscribe from on the lists page, and click the corresponding unsubscribe link. That's it!
In this case, Bob must use the following format :
nbusers-unsubscribe-bob=freemail.com@netbeans.org
Or, more generally, use
listname-unsubscribe-user=host.domain@netbeans.org
Where listname is the name of the list, like nbusers or nbdev, and user=host.domain is your original email address, with "=" substituted for "@", so bill@microsoft.com becomes bill=microsoft.com
For per-module mailing lists like dev@openide, the format looks like
dev-unsubscribe-user=host.domain@openide.netbeans.org
If you haven't already, submit a list query for your other email address, the results will include these special format unsubscribe addresses.
If you're not sure which of your email addresses is subscribed, you can find out by examining the headers of a list message. See the list FAQ for details.
nbusers-digest-unsubscribe-bob=freemail.com@netbeans.org
listname-owner@netbeans.org
so for example the nbusers list owner address would be
nbusers-owner@netbeans.org
