Newbie question
I understand there are methods that an email sender can be notified when their message is downloaded or read. Would someone please explain how this works and what software packages can be used to monitor this?
There may be times I would like to read an email without a notification to the sender that I read it.
As an email recipient is there a way to know if a notification is being sent, or which email messages are so monitored?
Is there a way to read an email without sending the notification?
If it means anything I use the pop3 protocol.
Just because I am paranoid, does not mean they are not still out to get me.
Thanks
Gary
