Applications, servers, and devices that wish to send email can do so using Marley - our authenticated mail relay service. Emails sent this way will pass all email authentication checks, meaning they are less likely to be marked as spam.

Our authenticated mail relay is available for any application or device in any location.

In order to use the SMTP Relay, your application must:

1. Support SMTP authentication (with the SASL PLAIN mechanism).
2. Support TLS encryption (STARTTLS).

Request an email-svcrelay account

Please submit a ticket with your desired service account name and a list of SIMS owners. DIT will create the account, which you will then manage in SIMS.

In a future update this will be a self-service operation. When this occurs, DIT will update the documentation accordingly.

Create a password on your email-svcrelay account.

1. Once you've received notification that your account is ready, login to SIMS
2. Scroll to Identities You Own and locate your service account.
3. Click the Reset Password button.
4. SIMS will generate and display a password. It will take about 5 minutes for this new password to take effect.

Configure your application to use the SMTP Mail Relay

• SMTP Server Address (or Hostname): marley.umd.edu
• Port Number: 587
• Enable authentication with:
  • Username: Your service account name (only the name - not an email address).
  • Password: Your service account’s password.
  • Authentication Mechanism: PLAIN
• Enable TLS encryption.
  • Method: STARTTLS
  • Please note - many applications automatically use STARTTLS when the port is set to 587, and may not have a way to explicitly enable STARTTLS. If no setting for STARTTLS is available - chances are using port 587 will implicitly enable the correct encryption method.
• Set your “From” email address to any @umd.edu email address.
  • This does not have to match your service account name - you can use the email address of a user, a group, a shared account, or noreply@umd.edu.
  • The address must be @umd.edu, using a subdomain like @example.umd.edu or any other domain is not supported.
