It was marked as a duplicate, so someone else must have made the same bug report. And, they use cyrus mailstore in their server product! To be fair, they have addressed the bug twice - but each time they've made it worse. There was originally a work around (give the group a name that is valid in headers), but then they broke that workaround. -- Ian Eiloart IT Services, University of Sussex x3148 ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
