Hi Vladimir,

I'm seeing the same error when I use the latest rc and the next branch,
syncing with the same IMAP server as you. It happens consistently if a
new message has been created or copied/moved locally. I haven't had time
to look into it yet, but I just thought I'd mention that I haven't had
this problem with version 6.3.2.1, which I've used for a long time, so
it appears to be a new problem.

Probably completely unrelated, but in case it matters... I've noticed
that the X-OfflineIMAP very often seems to get garbled (also with the
older versions that have been working fine for me). Take for example
these lines from the log you posted:

Received: from acsinet21.oracle.com (/141.146.126.237)
X-OfflineIMAP: 845261242-5859386199
	by default (Oracle Beehive Gateway v4.0)
	with ESMTP ; Thu...

Here, the X-OfflineIMAP header has been placed in the middle of a
Received header, so the second and third line of the Received header
become extra junk at the end of the X-OfflineIMAP header.
