sa-learn ham from my emails

[Daniel Caņas]

I have over 2000 emails that I have as ham and would like to feed to 
sa-learn..

The emails are all mine (that is they are addresed to me) is this a 
problem for sa-learn?

Will it learn the headers and mark my email address as a token for 
ham... causing bayes to not work correctly for my address?

I have legit spam that I want to learn but I am afraid to do it if I 
don't have corresponding number of ham.

I guess the question is:
Is feeding a bunch of emails addressed to a single person into sa-learn 
a good thing to do?
