The Internet Traffic Report monitors the flow of data around the world. It then displays a value between zero and 100. Higher values indicate faster and more reliable connections.

Viewing Full Headers

An e-mail message is divided into two parts, the "header" and the "body." Headers contain all the technical information, such as who the sender and recipient are, and what intermediate computer systems the message passed through on its way to the recipient's mailbox. The body contains the actual message. A blank line typically separates the header and body. In some mail programs, the headers are shown separately. Most people are only familiar with "friendly" e-mail headers, these are what you see in your mail program, typically the "To:" and "From:" lines. However, there is a lot of useful information beyond the "friendly header" contained in the "full header."

Most modern e-mail programs -- such as Eudora, Outlook and Netscape -- mask all but the From, To, Cc, Subject, and Date headers when displaying a message to the recipient, or when the recipient forwards that message to another e-mail address.

Viewing full headers can be helpful in analizing a problem (Duplicated Messages, Message dated in past, etc)

Looking at a sample header, we can determine useful information like where the message came from, when the server proccessed it, and the results of any additional filtering done by the server.

Received: via dmail-2000(11) for +INBOX; Sun, 13 Feb 2005 22:59:16 -0500 (EST)
This is the time the message was delivered to your "Inbox" on the server. Your client should have been able to see the message at this time.

Received: from localhost by mcnet.marietta.edu with SpamAssassin (version 3.0.0); Sun, 13 Feb 2005 22:59:16 -0500
Since this message was marked as "spam", the main message will come from our server.

From: Huntington Bank <customer.service@huntington.com>
The message claims to come from "customer.service@huntington.com", but these "from" addresses can be and commonly will be forged in spam messages.

Subject: *****SPAM***** [12.6 of 5.0] Huntington Bank - Security Update Notification
The subject tells you that the message was marked as "spam" and the score of this message (12.6) as well as the default spam score (5.0)

Date: Mon, 14 Feb 2005 05:58:31 +0200 (Sun, 22:58 EST)
This is the date in the message. This can also be forged. This field is generated by the origonating mail client and generally reports the date on the workstation of the sender.

X-Procmail-Finish: processed 021305 : 22:59:16
This is the time that the filtering system freed the message for delivery.

When a message is marked as "SPAM" by the server, it will rewrite the message to avoid the possiblity of your client running malicous code that may be contained within the message. The body of the message will contain information on "rule hits" and the scores associated with them. This is why the message was marked as spam. The origonal message will be contained within an attachement that will also contain headers. This is the format of most messages.

Received: from Asus (129.cablemodem-net02.cta.ro [193.108.234.129]) by marietta.edu (8.12.10+Sun/8.12.10) with SMTP id j1E3wgRS004524; Sun, 13 Feb 2005 22:58:43 -0500 (EST)
This message came from a machine at IP 193.108.234.129 that identified itself as "Asus", but in reality that address belongs to 129.cablemodem-net02.cta.ro. Obviously a cable modem. This most likely means that this came from a machine infected with a "spambot". We also see the time the message was delivered to our server for processing.

From: Huntington Bank <customer.service@huntington.com>
Again, this was forged and should not be trusted.

Subject: Huntington Bank - Security Update Notification
The origonal subject.

Date: Mon, 14 Feb 2005 05:58:31 +0200 (Sun, 22:58 EST)
This was the date reported by the origonating client. Again, this could be forged (or may simply be the difference in time zone.

X-Procmail-Start: processed 021305 : 22:58:57
This tells us the time that the server began filtering the message.

X-MCVirus-Scan: Scanned on 021305 : 22:58:58
This simply informs us that the message was scanned for viruses.
