Thank you for your support, Joseph Tam.

There is no other POP3 client connect to the server. In addition, when 
checking the log file, there is no "delete" or "expunge" action. It is 
very strange that after:
Nov 14 16:23:50 mail postfix/pipe[6257]: 143F1C0C60:to=ndpthanh at xxx.com> 
, relay=dovecot, delay=0.23, delays=0.01/0/0/0.22, dsn=2.0.0, 
status=sent (delivered via dovecot service)

the message disappear from New/Cur dir.

Hope to receive the advices from you.
