[boston-pig] Email error

[Brook, Robert]

Can anyone explain the inconsistent error that I get with this email code

import smtplib
fromaddress='robert.brook at domain.com'
toaddress='robert.brook at domain.com'
msg="subject: Hello\n\n\This is the body of the message."
a=smtplib.SMTP('HostName',25)
a.sendmail(fromaddress,toaddress,msg)
a.quit()


If I run this code interactively it works.

I if make it into a email.py file I get the error message

AttributeError: 'module' object has no attribute 'SMTP'

Thanks in advance
