ISC Networking and Telecommunications SMTP-Relay Service
ISC Networking & Telecommunications email service requires authentication for SMTP access. Certain devices which are capable of sending email
are not able to authenticate and therefore need an SMTP-Relay server
to accept mail. If you have such a device, please consider setting up your own SMTP-relay server.
Please see our documentation on configuring Sendmail.
If you cannot set up your own SMTP server,
smtp-relay.upenn.edu can be used:
- in those cases where the envelope sender and recipient are both
in domains that are hosted by ISC Networking and Telecommunications mail services. Those hosts are:
| ac.upenn.edu |
admissions.upenn.edu |
ben.dev.upenn.edu |
dental.upenn.edu |
| design.upenn.edu |
dolphin.upenn.edu |
ehrs.upenn.edu |
exchange.upenn.edu |
| gse.upenn.edu |
isc.upenn.edu |
mail.med.upenn.edu |
magpi.net |
| pobox.upenn.edu |
sp2.upenn.edu |
zimbra.upenn.edu |
upenn.edu |
In this case, there is no charge and no registration required to use smtp-relay.upenn.edu.
- by hosts which have been registered. In this case unauthenticated
email relaying to and from any sender and recipient connecting
from the registered host is allowed. There will be a monthly charge
for use of this service by registered hosts.
New hosts that wish to use SMTP-Relay will
need to fill out a registration form that requires PennKey authentication.
