Email Relay Policy

Email Relay Policy

Kettering has long had a no e-mail relay policy in place due to the possible unauthorized use of Kettering University's email server to flood the system with unsolicited, commercial Email. This means that we will not accept off-campus third-party Email, also known as relayed Email, except that one of the following items is true:

1. When you are (only) sending to "Kettering.edu" addresses, or
2. The message originates from a host in the "Kettering.edu" domain (I.e, you are on-campus.), or
3. You are using Google Mail, or
4. You use SMTP-Auth in your e-mail client and also possibly using port 587 (alternate SMTP sending port) in outgoing e-mail settings.

If you are using the services of an ISP, you should either be using Google Mail, or setting up your e-mail client to use SMTP-Auth with the SMTP port set to 587. (Using port 587 should work off-campus as well as on-campus. So leaving it that way should not cause you problems.) You should have fewer problems with incoming mail, and should, under most conditions, be able to fetch mail via a secure channel (SSL) POP client (POPs, port 995) from POPs server pop.Kettering.edu, or via a secure channel (SSL) IMAP client (IMAPs, port 993) from IMAPs server imap.kettering.edu. Your outgoing e-mail server (SMTP) should be set to mailhost.kettering.edu.
