http://www.msexchange.org -------------------------------------------------------This is called spam. This particular type is an account test. If your mail server does not respond with "we don't know dis dood" NDR, they assume the address is real and add it to their list. Get a good spam filter (IMF is free, but GFI Mail Essentials works great). -----Original Message----- From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of kimiagar Sent: Thursday, June 08, 2006 4:05 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Shall I use Recipient Filter? http://www.msexchange.org -------------------------------------------------------Hi All, I receive many emails in Administrator or Webmaster Mailbox as follows (This is just a sample one): ********************************* From: System Administrator To : Administrator Subject: Undeliverable:YOU HAVE SUCCESSFULLY UPDATED YOUR PASSWORD Body : Your message To: jerry@xxxxxxxxxxxxxxxx Subject: YOU HAVE SUCCESSFULLY UPDATED YOUR PASSWORD Sent: Thu, 8 Jun 2006 12:29:21 +0430 did not reach the following recipient(s): jerry@xxxxxxxxxxxxxxxx on Thu, 8 Jun 2006 12:26:51 +0430 The e-mail account does not exist at the organization this message was sent to.
