*Note: a sample for submission to Postini Spam Engineering must meet the following criteria:

  • In .msg, .eml, .mbox or RFC 5322/MIME format
  • Filtered by Postini service
  • The message did not trigger the Virus or Content Manager filters
  • The spam score was above the configurable range (scores over 2.0000)

How we use the sample files

Postini Spam Engineering uses the sample files to improve overall filtering, so you might not notice an immediate change for your domain.

Will I receive a response to my spam sample submission?

The Message Analysis Summary confirms whether or not your submission was successful, but only if your submission meets the criteria described above. If your submission does not meet the above criteria, a confirmation message is not displayed. Note that you will not receive a personalized response from a Postini Spam Engineer. Please know that we appreciate your time and effort in submitting the samples.
