# This line is simply using in your muttrc as follows:
#   mailboxes `~/.mutt/getfolders`
# Which will output something like:
#   mailboxes +2000/05/Inbox +2000/05/debian-user +2000/05/debian-ipv6
#
# This should make automatic mail sorting much easier to handle. Now you can
# easily deal with multiple mailing lists and monthly sorting.

# Set MBOX to "yes" if you use mbox instead of Maildir
MBOX=no

# Set to "yes" if you want to check last month's mail for new messages
#   NOT recommended unless you use Maildir - you'll have to uncomment
#   a portion of the code near the bottom if you REALLY want to use it
#   with mbox mail folders (will also require grepmail)
CHECKLAST=yes
