Q:
What is an e-mail header and should I pay attention to it at all?<\/strong><\/font><\/p>\n

A:
<\/font><\/strong>That's an excellent question! When you hear the word header, you may start to think about a subject line. Well, that's not the case when it comes to working with e-mail. A subject line is what you see when your e-mails first arrive in your Inbox. The actual header can be found when you open up the e-mail to read it.<\/font><\/p>\n

Now, you may not see it right away, because most of us don't have the option selected to see the header all the time. The headers can be quite lengthy, because they contain a lot of information about the sender, the receiver, etc. Here's an example of what an e-mail header looks like:<\/font><\/p>\n

See what I mean? It can all be a bit confusing, so allow me to explain everything to you just a bit more! Your headers may look a little different than the one above, but all of the information is similar, so you'll be able to at least get the gist of what I'm talking about today.<\/font><\/p>\n

Let's begin with the Return-Path <\/strong>line. If an e-mail ever has trouble going through (in the sending process), the Return-Path e-mail address is the one that should be used to try sending the e-mail again. Next is Received<\/strong>. That one shows all of the e-mail servers the e-mail had to go through to get to its destination (your Inbox). They usually include the server location and the IP address information. It also lists the date it was sent. That information is helpful in troubleshooting why an e-mail didn't go through in the first place.<\/font><\/p>\n

The next line is the Message-ID<\/strong> and it's the assignment that was given to the e-mail from the first e-mail server. Up next, you'll see the From:<\/strong> option. That's simply the e-mail address of who sent the e-mail and the To:<\/strong> line is who the e-mail is being sent to. The Subject:<\/strong> line just states what the original subject line was. Again, that's what you see in your e-mail Inbox before you ever open a message. After that, you'll once again see the date<\/strong> the e-mail was sent.<\/font><\/p>\n

Now, the sections after that can be a little more complicated. For any lines that start with the letter X, different things can be of importance. Here are some examples:<\/font><\/p>\n
