Step 2: Set up ETRN host and port

After signing up for the service, you need to set up ETRN host and ETRN port in the control panel. When your email server goes down, all your emails will be received by our servers and be delivered to the ETRN host on the ETRN port configured by you. Our email server tries every 10 minutes to deliver the queued emails.

Step 3: Add MX record

Email backup service for your domain name won't work until you add our mail servers as secondary MX records:

MX1.DYNU.COM
MX2.DYNU.COM


If your DNS is managed by us, MX records should have been added automatically when you sign up for email backup service. Otherwise, you can refer to this tutorial to add them in the control panel.

If your DNS is managed somewhere else, you can either transfer your domain name to us or contact your current registrar to add the MX records.
