These mailing lists, and the other Open Source Xen mailing lists, have for a long time used the domain name "xensource.com". This is rather out of date now :-) and also it makes the listserver produce links to some old list archives. So we are going to change the hostname which is used by the mailing list software in its outgoing messages, for example in the various headers like List-Id etc., and the mailing list footer. If you are filtering your list email you will probably need to update your filters. This change will take place some time in the next few days. NB this change affects only the contents of outgoing email headers, links, etc.; the mechanisms for subscribing/unsubscribing, and for posting to the list, will remain unchanged. But we would encourage people who want to post to the lists to use the address @xen.org rather the old one @xensource.com. Thanks, Ian.
