N-Able Mail Assure SPF Setup 

Sender Policy Framework (SPF) is an email authentication protocol that helps prevent unauthorized sources from sending email on behalf of your domain. It works by specifying which mail servers are allowed to send email for your domain, helping reduce spoofing and phishing attempts.

N-able Mail Assure supports SPF by checking the sending server’s IP against your domain’s published SPF record. To ensure email is properly authenticated and delivered, you need to configure your SPF record to include all legitimate sending sources.

This guide explains how to configure SPF correctly to work with N-able Mail Assure.

N-Able Mail Assure SPF Requirements

Important: N-able Mail Assure uses different SPF records depending on your region. To ensure accurate authentication and delivery, you must include the correct SPF include statement based on the region where your Mail Assure instance is hosted.

Refer to the list below and choose the SPF record that matches your region. If you’re unsure which region applies to your setup, check your Mail Assure portal settings or contact your system administrator.

These regional specific records are only to be used if you require a reduction in the scope of allowed IPs to a smaller geographic region.

ZA

In this example, we will be using the Global SPF record as an example.
 

Note: If you’re already using Sendmarc for SPF management, simply copy ‘include:spf.mtaroutes.com’ and follow the steps here.

To authorize N-Able Mail Assure to send emails on your domain’s behalf:

  1. Log in to your domain’s DNS dashboard.
  2. Go to the page where you can update the DNS settings on that domain.
  3. Check if a TXT record starting with v=spf1 already exists.
    • If it exists, modify the existing record to include N-Able Mail Assure (details in the table below).
    • If not, create a new TXT record.

Example of an updated SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:another.net include:spf.mtaroutes.com ~all

Example of a new SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:spf.mtaroutes.com ~all
  1. Save your changes in the DNS control panel.

Allow up to 48 hours for DNS propagation, depending on your DNS host.
