Hi

I have strange situation with one of mailboxes in mdbox format. Some
messages are duplicated, not all. I am sure that is not sieve or
another mail client issue, because access is via roundcube without
sieve plugin. In maillog I have not found any suspicious information about this
problem and i can see that from postfix do dovecot-lda was piped
only one copy of message.

I have a similar problem, but not the same (if this could give you a clue).

In my case I think that is fault of the email client (thunderbird).
I have some users with a lot of emails in some folders. These emails
are received from web applications that send a lot of of them. In my
case, the user receives them in his inbox folder and with a filter in
his client they are moved to another folder. This is where I think
that duplication are done (since one user move the filter from his
client to a sieve script in the server, there are no more duplications )
