@Email is a device that can be added and configured via Do-More Designer System Configuration/Device Configuration. It is super easy. If you know the server name of your Email host, the setup even has a DNS lookup tool, that will find the IP address for you. After the @Email device is setup, then there is an EMAIL instruction that will sit on the coil side of the ladder, that basically looks like you are composing an email message. Recipients, CC, BCC, Subject, Message, plus Success and Error bits. I'm sure others will explain it better than I, but if I can figure it out, I suspect most anybody can.
