Actually as i told there were two groups i have created in my mailserver
which contain a common emailid.
For example

group1: user1 at example.com,user2 at example.com
group2: user1 at example.com,user3 at example.com

If i am sending a mail to group1 and group2. It is going two times a
single mail to the user1 mailbox. But in dovecot it is not eliminating
since it has the same message-id. Previously i was able to accomplish this
task with cyrus duplicate elimination.
