[Dovecot] Files Moving From /New to /Cur

Using Dovecot 1.2-9 with Maildir and layout=FS.

We have our own delivery pushing messages to the /new and then /cur folder eventually. When I have an IMAP client attached, there is apparently some sort of race going on. I believe that Dovecot is moving files from /new to /cur (and renaming them) before our own delivery gets the job done.

This is causing a problem for us. Is there a way to disable this in Dovecot? I have the LDA section commented out of the config file..so I don't think that's in play. Bottom line is that I don't want Dovecot to move any files around whether an IMAP client is attached or not (except for handling the IMAP COPY/APPEND).

Regards,

Tony
