Help us help you: are you asking this because you have received email for which you think the source address is hidden? Or are you trying spoof your recipient?<br />
<br />
Crafting a spoof email is pretty easy: you just need to send forged information in the email headers when creating the message and bypass any mail programs that would prevent the forged email from getting through. Most of the time, this can be done by connecting to port 25 of your friendly mail server and speaking HTTP protocol, which is pretty easy.<br />
<br />
Doing this in a way that completely avoids detection, however, is pretty difficult and giving you detailed instructions on doing that would probably be considered abuse of Experts Exchange -- not that I think I could provide such instructions.

Regarding email source

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.

Internet / Email Software

Email Software

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
