this case is really suspicious to me. don't hang on the old date 2006-09-18. 
I can recreate it with dovecot 1.1.1 running on my machine.
I create completly new mbox, write to it and when i view mbox in console i 
see just this mail. After deleting (pop3) this mail with our webmailer or 
OutLook Express etc. I see this internal message with current date.
I do not belive in Clients that put internal mesages by pop3-protocol, but 
what should it be else? pop/imapserver is dovecot 1.1.1
And why this case just happens by updateing from 1.0.x to 1.1.1 and not 
during further updates from 1.0.x to 1.0.x+1  ?
If you say this is not dovecot related i have to accept this but i am a 
little bit doubtful...

Unfortunately i have now a more annoying error in imap processing. Sometimes 
it happens that dovecot seems to be out of sync.

Hmm, if we got more errors with 1.1.1 on our servers we have to downgrade to 
1.0.15 and stop installing new version and wait for 1.1.x
alltogether we have ~2000 servers, but most of them are running still 1.0.x

This is my configure-line, dovecot is packaged by my self

./configure \
--prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--mandir=/usr/share/man \
--with-ssl=openssl \
--with-storages=mbox,maildir,raw \
--with-pam \
--with-passwd


This is my dovecot.conf

##
## IMAP specific settings

protocol imap {

System is suse 10.1
