[Alpine-info] Activating Mail which was on Shellworld?

[Chime Hart via Alpine-info]

Hi All: This may be a little complicated? I had 7961 messages in an inbox on 
Shellworld, located in a directory Maildir/cur  all these items began with a 
number 1. So I zipped them up-and-downloaded to my local machine. My home 
machine gets its mail from Fastmail, eventually ending up in /var/mail/Chime 
the file Chime has all the current messages. So, even after unzipping in to 
that directory, those messages are not active in any folder. I would want an 
additional folder, maybe call it "rss" as majority of items are news articles. 
Once in a folder I can work on saving these articles to locations. Thanks so 
much in advance for suggestions.
