# This script provides a send-email function that allows you to use it in other scripts to send emails.
# It needs some configuration before use.
# Example usage:
# $from = "person@someplace.com"
# $to = @("person1@someplace.com", person2@someplace.com")
# $cc = @("person3@someplace.com")
# $bcc = @()
# $subject = "An Email Subject"
# $body = "<h2>This is the body</h2><p>It requires html tags.</p>"
# $priority = "Normal" # (Options are "Low", "Normal", and "High")
# $attachments = @("C:\path\to\file.txt")
# NOTE: If you are not using a CC, BCC, or attachments, please pass in an empty list, like:
# $attachments = @()
