There is any implementation of spf that checks the from of the data
transaction ?
Not that is actually useful. There are valid reasons for Mail From
and From
to be different (look at the header of the e-mail for example).
How can i prevent forged froms on the data transaction ?
This is a difficult problem. SPF is only a part of the solution to
a bigger
problem.
What MTA are you using? We might be able to suggestion specifics.
Postfix.
Thanks for your help.
