SMTP 451 error

[Iddo]

Hi All,

I am getting an SMTP 451 error when trying to perform the following
sendmail. It works on one machine, but raises a 451 retcode on
another. I included the smtplib debug info. ANy ideas?

Thanks,

Iddo

>>> smtp=smtplib.SMTP('localhost')
>>> smtp.setdebuglevel(1)
>>> smtp.sendmail('Iddo at bioinformatics.org','idoerg at cc.huji.ac.il','hi')
