About Header Fields
When messages are processed by the message service, custom header fields
are placed in email-message headers. This header information can be useful for
either determining email disposition or for handling support issues.
This chapter describes the following header fields added by the message service:
• “Received Header Field” on page 402
• “X-pstn-levels Header Field” on page 402
• “X-pstnvirus Header Field” on page 404
• “X-pstn-settings Header Field” on page 404
• “X-pstn-2strike Header Field” on page 406
• “X-pstn-xfilter Header Field” on page 406
• “X-pstn-neptune Header Fields” on page 406
• “X-pstn-addresses Header Field” on page 408
• “X-pstn-disposition Header Field” on page 409
• “X-pstn-nxpr and X-pstn-nxp Header Fields” on page 410
The service minimizes processing time by only scanning for categories that the
user has enabled. For example, if a user turns off the commercial category, the
commercial score is not completed or displayed.
All the numeric header values display 5 digits to the right of the decimal place.
Show Full Header in Gmail
Before you can examine a message, you need to show the full header in Gmail.
The full header is about 20-40 lines long and contains detailed information about
the mail message and its history.
