Hi,

Use reformail with "-x":

> Extracting headers
>
> The -x and -X options extract the indicated headers from the message,
and print them to standard output. Multiple -x and -X options can be
specified at the same time, and may be intermixed.
>
> The -x option extracts and prints the contents of the header. The -X
option prints the name of the header as well.
