Recently, I noticed that I was receiving Returned Mail messages from
various mail servers, saying that "host not found" or something like
that. This is not unusual, because of spammers using spoofed E-Mail
addresses on my domain.
What I found odd was that the message that was sent that caused the
"not found" error was a read receipt from Microsoft Outlook 2007
(which I use).
To test this finding, I sent myself a message with a read receipt
attached to it, but I didn't read the message and deleted the message
(which put the mail message in my Deleted Items folder).
When that message was cleared from the Deleted Items folder, a "not
read" receipt was sent back, even though I have Outlook set to prompt
me before sending read receipts.
This strikes me as an effective way for spammers to gather valid E-
Mail addresses even when Outlook's spam filter catches their messages.
The "not read" receipt is being sent, even though I have told Outlook
not to, which in my mind, constitutes a risk that Outlook shouldn't be
exposing me to.
Am I off-base with this? Is there a way to turn off the "not read"
receipt function that I'm not aware of?
I did a search, and found a similar bug report from 2003, and it
strikes me as odd that something like this wouldn't be fixed in four
years.
