Question: How can I manipulate the "from" field in an email and make the "to" user see something different then the actual.

Example: 

really from 

```
From: TStamper@yahoo.com

```

but they see

```
From: Tremayne "Top Dog" Stamper

```

I've heard its from manipulating SMTP, but really not sure how accurate that is or how it can be done

Answer: 
```
telnet some_smtp_server.com 25
ehlo whatsup
mail from: JohnBaker@yahoo.com
rcpt to: recipient@somewhere.com
data
your message here
end with a dot on a single line like this:
.

```

Of course you'll need an SMTP server that allows relaying, which is almost impossible to find... or roll your own (just don't use this knowledge to spam!).
Yes, it's by manually setting SMTP headers and is trivial to accomplish. Google it. But don't get caught spamming......
