This plugin will be usefull to make a link to articles in archive, but not to provide any archive index, so one could not use this as crossover list viewer. This is important feature on considering privacy protection in relation to personal data, including customer name, mail address, phone number, office address, and so on.
This plugin was used to depend on Setting#mail_handler_api_key to encrypt/decrypt the mail key, but now works with individual setting. Create an archive key on the plugin setting panel at first. Empty archive key makes no link to archive.
Use bin/import.rb to import new mails. This script scans its arguments as paths to mail data, and picks X-ML-Name and X-Mail-Count header variables, which are treated as Article#list and Article#count respectively. Path is expanded to absolute path, so be careful where the mail data is stored.
Enjoy!
