# Command to send to multiple email addreses simultaneously, separated by commas.
# However, if any email address has a colon in it, then the second email address overrides the first
#
# Ex:
#	user1@example.com,user2@example.com:user3@example.com,user4@example.com
#
# This will send to user1, user3 (overriding user2), and user4.
