These look like seperate messages. Look at the times in the logs, 20
minutes a part. A better check would be if I could see the whole log for
13:02:01 -> 13:04:00 and 13:22:24 -> 13:24:00

This should show the first delivery and then the second. The problem is
that Postfix can and does reuse it's message ids as they are based on
inode numbers. If your /var/spool/postfix partition is a bit small/ full
it will reuse the numbers faster. The theory goes that Cyrus should be
using unique message ids so there is no duplication. I know Postfix
generates another id when it delivers the mail it's self (To unix mailbox
or maildir) as opposed to handing off the the Cyrus delivery agent.

Hi Drew,
 What specific things should i look on the logs. Im getting 4 emails with the same message id. And im  using dovecot for my pop3 services. Like for example , i have these email tag as spam but i received 4 times with the same message id. is there something wrong with my postfix and Mailscanner?
