Setting up Outbound Email Relay

You can have your company's mail server use the Proofpoint Essentials SMTP server for outbound mail. This will use the same scanning as the inbound mail. In addition, using the Proofpoint Essentials SMTP service will allow you to see the messages in the logs as well.

The pre-requisite for performing an outbound relay is that the domains need to exist in the Proofpoint Essentials service prior to Outbound relaying. This is part of the two-tiered authentication we have for SMTP relay. 

Enabling Proofpoint Essentials Outbound Mail service

You need to make sure the service can use the outbound mail flow.  Follow these steps to activate relaying.

  1. Go to Company Settings.
  2. Go to the Features sub-heading.
  3. On the next page, check the box next to: Enable Outbound Relaying.
  4. Save your settings.

You are now enabled to use the Proofpoint Essentials server to use SMTP service.

 

Enable Relaying through Proofpoint Essentials

After relaying is enabled, follow these steps so the Proofpoint Essentials servers allow your IPs to send mail. This is how we authenticate that your mail server is allowed to send mail through our system.

  1. From the Company Settings area, go to Domains.
  2. At the bottom area labeled Sending Servers, press the Add New Sending Server button.
  3. Enter in a single STATIC IP that you will be relaying email from, and then save.
  4. Repeat step 2-3 until all your IPs are added in.

 

Once you have completed both sections above, please see Setup step 4 (configuring your mail server for SMTP usage with Proofpoint Essentials).

NOTE: Only static IP addressed and fully registered accounts will be accepted when sending outbound email - please verify these when opening a support ticket.
