Hi,
I'm testing Dovecot v2.3.9.2. So, I found a problem that a Dovecot process termed with Panic, like below:

It was occurred this by a mail had ISO-2022-JP content (Single part mail). I saw that the mail was not strange. When I appended the mail with IMAP APPEND command, that no problem happened. I think the problem comes by LMTP only.
Any idea?
