[Tutor] python smtplib 'Message denied - From address spoofing attempt detected via SMTP

[nitin chandra]

Hi All,

I am trying to script a confirmation mail on submission of a form.

Till now the form submission and summery page is working.

BUT the following 'section' is not working.
-- This is a python(CGI) script
-- hosted on a shared server on hostgator.in

-- This is giving "250 Spoofing error ....", below copy/pasted error
log of apache with respect to my website

*************** script ****************
import smtplib
