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 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:

mx.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:

128.46.105.218 (ARMS B191)
128.46.117.252 (CIVL B146)
128.46.88.3 (MJIS B067)
128.46.154.8 (MSEE 130H)
128.46.177.8 (POTR B16)

Pick one with the same subnet, and/or pick one in the same or closest building. Hopefully this will help the device be more successful in reaching an available e-mail relay host.
