# Generate a new message in the mail directory, with

# After this function returns, the filename of the generated message
# is available as $gen_msg_filename and the message ID is available as
# $gen_msg_id .
#
# This function supports named parameters with the bash syntax for
# assigning a value to an associative array ([name]=value). The
# supported parameters are:
#
#  [dir]=directory/of/choice
#
#	Generate the message in directory 'directory/of/choice' within
#	the mail store. The directory will be created if necessary.
#
#  [body]=text
#
#	Text to use as the body of the email message
#
#  '[from]="Some User <user@example.com>"'
#  '[to]="Some User <user@example.com>"'
#  '[subject]="Subject of email message"'
#  '[date]="RFC 822 Date"'
#
#	Values for email headers. If not provided, default values will
#	be generated instead.
#
#  '[cc]="Some User <user@example.com>"'
#  [reply-to]=some-address
#  [in-reply-to]=<message-id>
#
#	Additional values for email headers. If these are not provided
#	then the relevant headers will simply not appear in the
