This guide takes a brand-new JetEmail account and an existing Enhance cluster through every step required to send authenticated mail through the JetEmail relay. There’s no JetEmail plugin for Enhance, so the smarthost is configured directly from the Enhance UI.
Two ways to handle the many customer domains in an Enhance cluster:
  • Free tier: Add and verify every sending domain in the dashboard (step 2). Mail from any unverified sender will be rejected. Workable for a small cluster, painful as customer count grows.
  • Pro subscription: Enable Allow any domain on the SMTP user (step 3). The smarthost can send from any customer domain without preconfiguring each one in the dashboard. You still need SPF published on every sending domain (see step 3) — Enhance has no plugin to do this for you, so plan the SPF rollout yourself.
See SMTP users → permission modes for the full comparison.
1

Sign up for JetEmail

Create an account at jetemail.com, then open the dashboard at dash.jetemail.com.
2

Add and verify your sending domain

  1. In the dashboard, go to Outbound → Domains
  2. Add the domain you send from (e.g. example.com)
  3. Publish every DNS record the dashboard shows (SPF, return-path, DKIM, DMARC, feedback) at your DNS provider
  4. Wait until the domain shows as verified
For a full breakdown of the records, see Email authentication.
3

Create an SMTP user

  1. Go to Outbound → SMTP in the dashboard
  2. Click Create SMTP
  3. Set a Username and strong Password
  4. Leave Quota at 0 for unlimited, or set a per-user limit
  5. On Pro plans, toggle Allow any domain on so the smarthost can send from every customer domain in the cluster without each one being verified in the dashboard. On the free tier, leave this off and make sure every customer domain you intend to send from has been added and verified in step 2.
With Allow any domain on, you skip per-domain dashboard verification but each sending domain still needs SPF published at its DNS provider (see SMTP allow any domain). Enhance has no plugin to publish SPF for you, so plan how you’ll roll it out across customer domains before flipping the smarthost on cluster-wide.
Keep the username and password ready for the next step.

Configure the smarthost in Enhance

  1. In Enhance, open Servers in the left sidebar
  2. Click Manage on the server you want to configure
  3. Open the Email role
  4. Click Settings
  5. Enter the smarthost details:
    • Smarthost: relay.jetsmtp.net
    • Port: 587 (or 25)
    • Username: Your JetEmail SMTP username
    • Password: Your JetEmail SMTP password
Inherited global settings show a Default tag. Once you override them on a specific server they no longer show that tag.
Apply the same settings to each server in the cluster, or set them at the cluster level so new servers inherit them.

Send a test message

Send a message from a mailbox on the configured server to an external address and confirm it lands. Then open the JetEmail dashboard’s Logs view to confirm the message was accepted and authenticated.If something looks wrong, the SMTP block error reference explains the most common rejection codes.
