multiple messages recieved

[B . Negrão]

Hy all,   All my virtual e-mail account clients are complaining about recieving multiple messages sometimes. They don't recieve the same amount of multiple messages, and not all the time. It seems to happen "randomly".  I use vpopmail to administrate my virtual accounts.   I by myself got this error when I was mading some tests: I sent various messages to one test email account, everything worked fine, suddenly, in one test, I sent from my outlook express 1  message to that email account. When I listed his maildir, I saw he recieved 4 times my single message. The messages have subtle diferences in it's headers(in red). I don't know how to interpret it. Could someone help me? Bellow, are the 4 messages headers. thanks!   the first: name: 978041164.20999.falcon,S=2292   Return-Path: <[EMAIL PROTECTED]> Delivered-To: [EMAIL PROTECTED] Received: (qmail 20997 invoked from network); 28 Dec 2000 22:06:04 -0000 Received: from 14bis.plugway.com.br (HELO 14bis) (200.195.39.9)   by falcon.plugway.com.br with SMTP; 28 Dec 2000 22:06:04 -0000 Message-ID: <000c01c0711a$aa4c7640$[EMAIL PROTECTED]> From: =?iso-8859-1?Q?B.Negr=E3o?= <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: teste Date: Thu, 28 Dec 2000 20:08:10 -0200     message 2: name: 978041548.21061.falcon,S=2395   Return-Path: <[EMAIL PROTECTED]> Delivered-To: [EMAIL PROTECTED] Received: (qmail 21059 invoked by uid 0); 28 Dec 2000 22:12:28 -0000 Delivered-To: [EMAIL PROTECTED] Received: (qmail 20997 invoked from network); 28 Dec 2000 22:06:04 -0000 Received: from 14bis.plugway.com.br (HELO 14bis) (200.195.39.9)   by falcon.plugway.com.br with SMTP; 28 Dec 2000 22:06:04 -0000 Message-ID: <000c01c0711a$aa4c7640$[EMAIL PROTECTED]> From: =?iso-8859-1?Q?B.Negr=E3o?= <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: teste Date: Thu, 28 Dec 2000 20:08:10 -0200     message 3: name: 978041657.21087.falcon,S=2395   Return-Path: <[EMAIL PROTECTED]> Delivered-To: [EMAIL PROTECTED] Received: (qmail 21078 invoked by uid 0); 28 Dec 2000 22:14:17 -0000 Delivered-To: [EMAIL PROTECTED] Received: (qmail 20997 invoked from network); 28 Dec 2000 22:06:04 -0000 Received: from 14bis.plugway.com.br (HELO 14bis) (200.195.39.9)   by falcon.plugway.com.br with SMTP; 28 Dec 2000 22:06:04 -0000 Message-ID: <000c01c0711a$aa4c7640$[EMAIL PROTECTED]> From: =?iso-8859-1?Q?B.Negr=E3o?= <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: teste Date: Thu, 28 Dec 2000 20:08:10 -0200   message 4: name: 978041657.21089.falcon,S=2498   Return-Path: <[EMAIL PROTECTED]> Delivered-To: [EMAIL PROTECTED] Received: (qmail 21085 invoked by uid 0); 28 Dec 2000 22:14:17 -0000 Delivered-To: [EMAIL PROTECTED] Received: (qmail 21059 invoked by uid 0); 28 Dec 2000 22:12:28 -0000 Delivered-To: [EMAIL PROTECTED] Received: (qmail 20997 invoked from network); 28 Dec 2000 22:06:04 -0000 Received: from 14bis.plugway.com.br (HELO 14bis) (200.195.39.9)   by falcon.plugway.com.br with SMTP; 28 Dec 2000 22:06:04 -0000 Message-ID: <000c01c0711a$aa4c7640$[EMAIL PROTECTED]> From: =?iso-8859-1?Q?B.Negr=E3o?= <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: teste Date: Thu, 28 Dec 2000 20:08:10 -0200       -------------------------------------------------  -- Bruno Negrão -- Suporte  -- Plugway Acesso Internet Ltda.  -- (31)34812311  -- [EMAIL PROTECTED]
