You should configure the mail_log plugin to log all actions clients do
to your mails: http://wiki2.dovecot.org/Plugins/MailLog

I've had to debug similar problems in the past time (on a different IMAP
server) and in _all_ cases it was something the user did, like having a
client downloading the mails via POP3 (and forgetting about this) and
complaining about missing mails from "the Webmailer Website". Or having
configured a filter inside Thunderbird (and forgetting about this),
instructing the client to delete mails matching a special rule.

If there is a reference in this file, the mail must have reached
dovecot. So the next step would be to find out, _what exactly_ the
client does with it. See mail_log again.
