[imp] Displaying usernames in message headers

[Marcius D. Moraes]

Hi,

I've posted a message last Friday but I had no response, maybe because 
my e-mail was confused. So I'll try again :)
Is there a way to put the real username in the header of messages sent 
by IMP?
E-mail addresses can be easily forged and so I want a method to find out 
the real senders of these messages.

Thanks
