[horde] Message Not getting Delivered

[Shardul Adhikari]

Hi,
I am facing a typical issue when forwarding a mail , mail which is being
forwarded does not get delivered to user id .
On checking the logs it comes as message is marked as duplicate , hence it
is not getting delivered ,
i am using cyrus-imapd as backend
Has anybody faced such an issue or anybody has any pointer to this
Thanks and Regards
