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:
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:
18.104.22.168 (ARMS B191) 22.214.171.124 (CIVL B146) 126.96.36.199 (MJIS B067) 188.8.131.52 (MSEE 130H) 184.108.40.206 (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.
