Ok, the message has the following text:

But every message in such a box marked as "Status: RO"

Please, help me to solve this trouble.

Looks like this is a message from pine.

I just deleted it.

Ciao, Gerhard

Hello!

I see the internal message from pine with the following subject (mbox format, dovecot 1.0rc22): DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA

As far as I know this message should be filtered.

I never saw this before in previous 1.0 betas and 1.0rc (nearly every version tested).

It's filtered if it's the first message in the mbox and it has X-IMAP header.
