Sending Email through the Grad/Research Network

INTRO

Secure, TLS-based password authenticated SMTP is available on the Grad/Research Net mail server. This

Our SMTP server is the mail server to use when you're sending mail with your@cs.jhu.edu email address.

You authenticate to the SMTP server with your Grad/Research Net CS account.

As mentioned, sending email as an @cs.jhu.edu user will work through our SMTP server. However, sending as other email addresses may not work, as the mail may not be accepted by the recipient due to various restrictions at the recipient's end. (Some remote mail services expect that email sent through an SMTP server be addressed using the SMTP server's domain.)

If You Are Sending Through The CS SMTP Server Using an @jhu.edu Email Address

Due to security changes to JHU's own mail servers, if you use the CS SMTP server to send email, but as an @jhu.edu user, you run the risk of your email not being accepted at your destination due to JHU's implementation of SPF records.

If you want to send email as an @jhu.edu user, please use JHU's SMTP services instead: http://www.it.johnshopkins.edu/services/email/microsoftexchange/QuickStart

Otherwise, please use your @cs.jhu.edu email address to send email through the CS SMTP server.

CONFIGURING CONNECTION TO OUR SMTP SERVER

Configure the following settings on your mail client:

• Server Name: smtp.cs.jhu.edu

• Port: 25 or 587 (should work with either, but 587 is preferred.)

• Security Settings: TLS password authentication. (You might see this as STARTTTLS.)

• Authentication: Set your mail client to authenticate (using your CS username/password) when sending mail through our smtp server.

Using the above settings will allow you secure login to the e-mail system from inside CS or from outside on the Internet.
