So do you have Edge server in place?... and your scanner will connect to public IP or have connectivity like VPN tunnel between Exchange and external site?

1. If using public IP address then Edge will receive e-mail using SMTP on 25 port without configuring anything because it will accept e-mails from and to address for accepted domain.

2. If scanner can be reached to internal Exchange IPs then create one receive connector on Hub transport where you will allow scanner IP in relay then allow authentication mode anonymous.

The copier need an smtp server for sending the email.
Amit KumarCommented:
use your Hub transport server if copier is able to reach.
