Documentation

Regexp to match X header fields that Rmail should show.

This regexp overrides rmail-ignored-headers; if both this regexp and that one match a certain header field, Rmail shows the field. If this is nil, ignore all header fields in rmail-ignored-headers.

This variable is used for reformatting the message header, which normally happens once for each message, when you view the message for the first time in Rmail. To make a change in this variable take effect for a message that you have already viewed, go to that message and type M-x rmail-toggle-header (rmail-toggle-header) twice.
