Here are some more details about the
Show details feature in the Fastmail web interface. You can see the
Show details feature if you select the Standard, Dark, Large Font, or Minimal theme in the
Settings>General>Preferences>Theme screen. If you use the
Classic theme you will not see the
Show details button and the extra headers shown below will always be shown:
- The normal display shows the following:
- Subject header
- From header display name (or local-part of From address if there is no display name)
- To header display name (or local-part of From address if there is no display name)
- Date (or time if recent) the message was received (in your timezone)
- Show details displays the following (by default):
- The information described above for the normal display and a temporary display of the following:
- From full header
- To full header
- Subject full header
- Date and time the message was received (in your timezone)
- Size of the message (not shown in any header and always displayed at the bottom of this list)
- In the Settings>Mail>Preferences>Reading>Extra headers screen you can add additional headers which will appear when you click Show details between Date and Size. Some additional headers you might consider adding include:
- X-Spam-Score (also shown before Subject when a message is in the Spam folder)
- X-Spam-Known Sender (yes if the From address is in your address book -- group and hex code used in sieve for that group is also shown)
- X-Spam-Hits (SpamAssassin hits and Bayes database information)
- X-Spam-Source (sending server IP, hostname, country, and top level domain names)
- X-Mail-From (envelope-From address)
- X-Delivered-To (envelope-To address used even during BCC)
- X-Resolved-To (target address after alias targeting and subdomain addressing conversion to plus+address)
- You can toggle the Show details feature on/off using the : (colon) keyboard shortcut.
- If you enable the Classic theme you will always see the extra headers described above and the Show details button will not be shown.
