Email, unauthenticated SMTP for Campus printers, web services, etc...
This page contains information about outbound-relays (aka Express-SMTP), an email service for on-campus IP addresses.
On This Page
Outbound-Relays.techservices.illinois.edu and Express-SMTP.cites.illinois.edu are the same Simple Mail Transfer Protocol (SMTP) server. This SMTP server allows computers or devices in the campus IP network to send "outbound" email without authenticating, hence your device doesn't need a NetID and password to send email. That said, the device or service needs to be properly configured and have a campus IP or connected to campus via the VPN service.
Who can use Outbound-Relays to send outgoing messages
Any computer, printer, web service or email client in the campus IP space can use Outbound-Relays to send outbound email messages.
Configure your on-campus printer or other device to use Outbound-Relays
requires an encrypted connection:
|reply email address:||Your service address or email@example.com. Email sent to no-reply is discarded by the email relays.|
Limits: Since this is a shared resource on the campus, there is a limit of 50 connection per server and 100 messages per connection.
Configure a desktop email client to use Outbound-Relays to send outgoing messages
It is best to use the default configuration for Exchange/Outlook(faculty, staff, grads) and Google Apps (undergrads). However, if your computer is on "campus only" then you can configure your client to use the express SMTP by substituting outbound-relays.techservices.illinois.edu for the outgoing email server. See the email client instructions for specific instructions.
