That's probably the problem here. The user had LOTS of (duplicate!) mails in his inbox.
Anyone ever found a reliable way to do this?
It sure would be nice if dovecot could perform this on a per account and/or per maildir/mailbox case with a simple doveadm command...
The basic question is: what is a duplicate?
I spot 100% duplicates within the same Maildir mailbox with a script similiar to "fdupes" http://linux.die.net/man/1/fdupes . Because an user may copy messages around, I scan one mailbox at a time.
For some rare cases, where I merge two accounts, I use a script, that looks for the message id in one account and removes all messages with the same id in the other account. Than I merge the Maildirs.
However, neither script I would call general enough for automatic processing
dbmail has just "suppress_duplicates = yes" and silently ignores *new received* messages with the same message-id to the same user as a global setting
that's fine for people not able to handling a mailing-list and hit reply-all every time
