If a domain is configured with an incorrect next-hop address, incoming email to be forwarded to the incorrect address is deferred. To fix the problem, update the domain specification by replacing the incorrect next-hop address.
Caution
Do not delete an existing MTA domain in order to fix an incorrect next-hop IP address. Doing so deletes the email that was deferred for the domain.
This procedure describes how to use the Settings > Email MTA page to update a domain and next-hop IP addresses.
Prerequisites
An established connection between the appliance and the Internet.
You are logged in to the appliance Web UI as an Admin or Operator.
Go to the Settings > Email MTA page.
In the Current Domain and Next‑Hop section, click the
icon for the domain that you want to update and select Edit.In the Update Domain and Next-Hop section, you can change the following settings for the selected domain:
Include Subdomains checkbox
TLS Delivery Mode
Note
The Verify delivery mode is not supported for domains that forward incoming message to multiple MTA hosts.
Enable Next-Hop MX Lookup
Next-Hop and Weight%
For a domain that specifies multiple IP addresses, the total of the weighted values must equal 100.
Click Update.
To verify your configuration changes, check the new entry that appears in the Current Domain and Next-Hop table.
