Sender-ID does not validate MAIL FROM.  So it is unaffected by
whatever you do with MAIL FROM.

However, Sender-ID wants you to do something similar with the 'Sender' 
mail header field.

Those other protection schemes are concerned with the RFC2822 mail
headers fields.  They don't validate MAIL FROM (except SES).
