I am using fetchmail to retrieve emails off server and then viewing with mutt. My settings look like,
poll server.com protocol IMAP user "firstname.lastname@example.org" password "secret" keep mda "/usr/bin/procmail -d %T" ssl
Everytime I run fetchmail it downloads all emails again, not just new ones that I haven't downloaded yet. How do I make this happen? Is this something I need to do in procmailrc?
