mailing list or community for the yaz client

[gurucubano]

Hello,
We use the yaz-client (in version 5.15.1) to test our own Z39.50 target software and to test connections of our Z39.50 origin software to remote targets. I'm looking for a mailing list of community to discuss certain questions. The mailing list from the README file http://lists.indexdata.dk/cgi-bin/mailman/listinfo/yazlist seems to offline.
Thanks
Matthias
