Hi, On our cyrus 2.3.7 servers we are seeing legitimate mails getting duplicate eliminated. Some users continue to use non-compliant clients which use duplicate message-ids. Is it possible to auto-expire records in deliver.db after say 3 hours so that these losses could be minimized ... the current minimum is 1 day AFAIK I cannot switch off duplicate elimination because that would cause problems to all other users too. (I know I should tell users to upgrade email clients .. but that is not going to work in reality ) Thanks Ram ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
