Change e-mail display name

[ZMAN2]

Is it possible to programatically change the name displayed before sending. For example, when the recipient receives the e-mail it displays from "XXX" as opposed to "YYY" set in outlook. I guess sort of like e-mail spoofing, but not really. It's just a displayed from change. Does that make sense..... Also, I did a search and didn't find what I was looking for....I'm probably just not asking the right question, so forgive my failed search attempt.

Thanks in advance.
