mail.log

... dovecot: imap(USER@DOMAIN): Connection closed: read(size=7992) failed: Connection reset by peer
  (UID FETCH running for 0.010 + waiting input/output for 0.040 secs,
  0.001 in locks, 60 B in + 433904+8192 B out, state=wait-output) in=200 out=435217

原因 Client 與 Serve 之間有 filter !!

開啟 debug mode 後會見到

... imap(USER@DOMAIN): Debug: INBOX: Mailbox opened because: SELECT

所以 "UID=54394" 那 mail 有問題
