# Takes the source file with full path as firtst argument.
# The file must be in a cur directory
# The scripts move the file from
# /srcpath/cur
# to
# /dstpath/.YYYY.MM.DD
# It reads the date from the "Date: " header in the message
# It resets flags from original filename, so all files are Unread
# It avoid overwriting
# Tipically this script is launched using:
# find /srcpath/cur/ -type f -exec move_maildir_from_cur {} \;
