Apologies in advance if this goes on a little long, but I’m a little
mystified by this.
I got a piece of vendor email spam today in my NU Office 365 Exchange account
a little after 10am. I have my mail client (Apple Mail 12.4) set to not load
remote linked content like images so that marketing people won’t know when
I’ve opened/read their messages. I read the message and moved it to my
vendor spam folder on the server. I thought that was the end of it.
Again, I’d check the log files and build a timeline.
About a half hour later, I got another email from the same vendor asking if I
had time to talk, and his email message quoted what looked like a message
from me saying that I had read the message! I never got a Read Receipt
notification in Apple Mail, and I looked through the raw source of the
original message and didn’t see any linked content or read receipt headers in
it either. So I have no idea how this vendor got notified that I had
actually read the message.
Attaching both messages in case anyone wants to take a look themselves.
Additional information: I also run Windows Outlook in a VM, where I also
check my NU Exchange account. It was set to display the calendar, so it
wasn’t displaying any mail. I also checked the settings there to ensure that
I wasn’t set to send Read Receipts automatically as detailed at
. When I did open the original message in Windows Outlook, I was not
prompted to send a Read Receipt.
