Gnus has the feature to export the mail to file with "O m" (gnus-summary-save-article-mail) command. I've been often using this feature to save the mail to the file for future reference.
However, I could not find the proper way to open the saved mail file with Gnus, so that we can properly extract the attached files, display with proper faces (colors), etc.
I appreciate if anyone knows and let me know how to do it.
regards,
