After a multi-hour download, I have in a directory of the local machine roughly a gigabyte (1000 megabytes) of email. The mail is in Maildir format. Much of the mail is spam or junk. However, the mail includes some important emails, so searching and sorting is necessary. The local machine is running Debian Jessie with the xfce desktop, and Mutt is running. What is a reasonable approach to culling spam and junk from the downloaded mail? RLH
