Setting up devices to send e-mail
When configuring a device to send e-mail, such as a multi-function printer/scanner system, use the following advice to set up the e-mail relay host.
The idea is that a device needs to send e-mail reliably. To do this, it would be beneficial if the device used the name of the e-mail relay hosts instead of a single IP address so that if the e-mail relay host is down, the name will translate into multiple IP addresses and the device will try multiple servers.
So here is the recommendation:
1. The device should be added to the access list on one of our servers (harbor) and have an ecn.purdue.edu name associated with its IP address, or it will be slow or troublesome sending e-mail. To allocate a hostname, send a request to the ECN software staff.
2a. If the device can be programmed with a host name, the device should set the e-mail relay host to:
Do not select any authentication (Use SSL/TLS: Off), and use the default port number of 25 for SMTP. Please provide a meaningful email address as the "from" address, such as its room number/printer name or department, with the suffix @ecn.purdue.edu
Do not use the host name smtp.ecn.purdue.edu - smtp.ecn.purdue.edu requires authentication always. Also, do not use the specific e-mail relay hosts named mxnn.ecn.purdue.edu (such as mx01, mx02, etc.) as they translate into a single IP address and become a single point of failure.
2b. If the device can only be programmed with an IP address, use one or more of the following addresses:
Pick an IP address on the same subnet as the device if available. Hopefully this will help the device be more successful in reaching an available e-mail relay host.
