Issue
- There is one option called "duplicatesuppression" in /etc/imapd.conf. Currently in our environment its turned off. As its turned off if users name is there in to or cc and in distrubution lists(DL) , user currently receives same mail twice.
Could you please guide about this option?.
- If we turn on this option in cyrus configuration will there be any performance impact on server?
