If you have not configured Alpine/Pine to show full headers before:
- From the main menu click Select setup.
- Choose config; you will have a lot of options to choose.
- Go to the feature list and turn on enable-full-header-cmd (pressing Return will do it).
If it is already selected (i.e. there is a cross by the item), do nothing. - Exit Setup.
You have now configured Alpine/Pine to show you full headers whenever you need them.
To show full headers in an individual message:
- Select the message in the usual way
- Type H
If you want to turn off full headers for this message, press H again.
If you need to look at full headers another time you will just need to press H when the message is displayed.
If you want to forward a message with full headers you will be asked whether to include the headers as an attachment. You should answer No to this.
