Email Deleted Without Being Read

  • 772

We have some automated software that checks certain Exchange 2007 mailboxes via POP3. When a customer's incoming e-mail requests a read receipt, Exchange seems to be sending back a non-read receipt. 

Not read: <subject> 
Your message was deleted without being read on...

The order in which the software issues POP3 commands is 

USER 
PASS 
STAT 
UIDL 
TOP # 0 
LIST # 
RETR # 
TOP # 0 
RSET 
DELE # 
QUIT

Our exchange administrator has been able to duplicate this issue via raw POP3 commands over telnet, port 110. The commands he ran were simply 

USER 
PASS 
STAT 
RETR # 
DELE # 
QUIT

Does Exchange 2007 translate POP3 commands to read flags? If so, it should tell that I've issued a RETR command to retrieve the message. Is this a bug? Is there a way to disable the sending of read receipts for specific mailboxes or globally?

    This looks to be an interesting problem. I found a few links to ansewrs, but it looks like this one is the best of the bunch. MSexChange

    Synopsis...

    a sure fire way of ensuring read receipts are not sent to external people is to configure FOUR transport rules... Rule 1:
    From users outside the organization
    Remove header "X-Confirm-Reading-To"
    Rule 2:
    From users outside the organization
    Remove header "Disposition-Notification-To"
    Rule 3:
    From users outside the organization
    Remove header "Return-Receipt-To"
    Rule 4:
    From users outside the organization
    Remove header "Receipt-Requested-To"
