We see it here as well, though I'm not sure it's exactly the same problem. It's always been a very short message with incorrect headers, _no_ subject header and no message body. Dovecot can't digest it.

I've been having this problem for a long time now. It started when I first began to use Dovecot (0.9x) and seems to have been occurring more and more frequently as we've progressed through the betas and now into RC7. I have been kind of chaulking it up to a "user issue" since the problem only seems to occur for one user (who has one machine at his office, and one at his weekend cabin... problem occurs with equal frequency on both of his machines). Lately it's been occurring about once every couple of days, but still nothing that I have been able to reproduce with any particular email or frequency.
However as luck would have it the problem occurred today while I was onsite at the client's office so I was at least able to see that end of things at the same time.
Essentially the user will have a number of messages in their mailbox (today for example 13) the download of mail will go just fine until one particular message and then the download will just stop, eventually returning an error message. Trying to receive mail again will retrieve messages 1-9 again and fail in the same spot. If you log in via IMAP and delete the following message (ie. the message after the one that was last received) you can then POP for mail again and the remaining messages in the mailbox will download.
In the log all we see is the following (over and over)...
Aug 28 16:14:51 mail dovecot: pop3-login: Login: user=<xxxxx>, method=PLAIN, rip=vvv.www.xxx.yyy, lip=vvv.www.xxx.yyy Aug 28 16:15:32 mail dovecot: POP3(xxxxx): Disconnected top=0/0, retr=9/170375, del=0/13, size=1349520
From the client side I get the following in Outlook Express...
"Your server has unexpectedly terminated the connection..." "...POP3, Server Response: '+OK 795 octets'..."
Interestingly 795 bytes is the size of the "bad" email (the one that won't download).
Any thoughts?
Cheers,
