-- First download the image we'll be adding to the HTML "img" tag.
local bdJpg = chilkat.BinData.new()
local http = chilkat.Http.new()
local success = http:quick_get_bd("https://www.chilkatsoft.com/images/starfish.jpg", bdJpg)

-- Use your SMTP server..
mailman.smtp_host = "smtp.yourserver.com"
mailman.smtp_port = 587

-- Set the SMTP login/password
mailman.smtp_username = "my_login"
