I'm pretty sure the userid is used as the user name when authenticating on
connection to the mail server, the same way you have to supply a userid when
connecting to your ISP using dial-up connection.

well, the raw smtp conversation goes:

$ telnet smpt-server 25
helo myservername
mail from: me <email@addy>
rcpt to: them <email@addy>
data
From: enter any headers here
To: this is display only
Date: this is where some exploits can be done with outlook

Put your message after the blank line
end your email with <CR><LF>.<CR><LF>
.

--

So it could be that NMSMTP1.UserID is possibly used in either the helo or
mail from: lines...
