Anyone know where I can read up on email headers? I'm using Outlook.
When I email myself, I'm able to find the IP address of my home router in the header, which is sometimes the IP address of my computer when I'm hooked directly into my cable modem. I'm wondering if this is always the case.
In one of the emails I received, one of the IP addresses under "Received" read: 5.5.2653.x ... What's the deal with that? The four digits that is?
Also, I noticed that sometimes different email headers have different numbers of "Received: from" and "Received: by" lines. Is there any reason for this?
I'm mostly concerned with if I can regularly obtain a person's IP from their emails. As mentioned above, I know I was able to get mine. If anyone knows of some good additional reading on the subject, i'd appreciate it.
Just so you don't think I'm getting ready to do something malicious, I run a message board, and I'm trying to match up IP's with posters who have previously been banned (and went and signed up under a different username and email), by comparing the IPs in their previous emails to me with IPs being used on the board.
Thanks.
