Like any organisation, I have a number of devices ranging from routers to switches, printers to multifunction centers, and some applications/scripts that send email via SMTP.
Some devices have no authentication mechanism in their software, while others offer windows credentials, and some support TLS. I have been doing quite a bit of research on this and some suggestions either don't work, or are ill advised. On one MS forum the "Moderator" confessed they had no idea how or if it could be done.
So what is the best way, and can it be provided as a step by step method. I've set them up in the past with since Exchange 5.5, 2000, 2003, 2007, 2010 but cant crack it in 2013. Judging by the number of hits on topics around this I am not in the minority.
I manage many sites that have the same types of devices making migration to Exchange 2013 a risk - so is it possible at all with Exchange 2013 - or do we exercise our downgrade rights to 2010 so that our major devices like the Multifunction centres can work in the way intended.?
To date I have tested Receive Connectors with the following properties
- Custom Connector
- tried both Hub and Frontend transport roles
- With no Security, Basic Security, TLS Security (for those devices that supported it)
- Permission group = anonymous
- Remote Network settings = All Internal IP Addresses
- Left Adapter bindings as defaults (all avail IPV4)
