# FileDelivery class delivers emails into multiple files based on the destination
# address. Each file is appended to if it already exists.
#
# So if you have an email going to fred@test, bob@test, joe@anothertest, and you
# set your location path to /path/to/mails then FileDelivery will create the directory
# if it does not exist, and put one copy of the email in three files, called
# by their message id
#
# Make sure the path you specify with :location is writable by the Ruby process
# running Mail.
