How do I unsubscribe?

[Sikora, Gary]

How do I unsubscribe from this service?  I've made several attempts to unsubscribe following the instructions on http://xml.apache.org/axis/index.html (there's really no instructions other then a link to a blank email) but I still receive up to 50 emails a day.  What do I need to do to get off this list?  My only other alternative is to consider this SPAM and block it at the firewall - I really don't want to do because this will adversely affect other members of my organization, and I hope we do not have to consider this SPAM.   Please help!
