The "fix" for this is to use M$-Exchange 2000 SP1 or later; their MTA (on the server) rewrites the Message-ID of the submitted message to a unique value. Someone told me there is an issue with re-using Message-IDs in the DSN functionality too, but I've never seen that one. -- OpenGroupware developer: awilliam@xxxxxxxxxxxxx <http://whitemiceconsulting.blogspot.com/> OpenGroupare & Cyrus IMAPd documenation @ <http://docs.opengroupware.org/Members/whitemice/wmogag/file_view> ---- 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
