Account Setup - How to Configure Custom Email Domain

Overview

This guide outlines the process for configuring DNS records to enable outbound email sending via a custom domain. PortPro supports sending system-generated emails (e.g., invoices, status updates) from a custom domain. Once configured, these emails will appear to originate from the configured domain rather than the default "do-not-reply@portpro.io," enhancing brand consistency and professionalism.

Domain Verification

Before configuration, the domain must be verified to confirm ownership:

• Contact PortPro Support via chat or email and provide the following information:

  • Domain name.

  • Verification Email
    A valid email address under the intended domain must be provided. A verification email will be sent to that address. Once received, the message must be forwarded to support@portpro.io to complete the domain verification process.  

  • A unique TXT record value (Record #4) will be issued for verification.

Required DNS Records

Access the domain registrar’s DNS settings and add the following records:

• Record #1
  Type: CNAME
  Name: mte1._domainkey
  Value: dkim1.mandrillapp.com

• Record #2
  Type: CNAME
  Name: mte2._domainkey
  Value: dkim2.mandrillapp.com

• Record #3
  Type: TXT
  Host: _dmarc
  Value: v=DMARC1; p=none

• Record #4
  Type: TXT
  Host: @
  Value: Provided by PortPro Support

Final Configuration in PortPro

After DNS setup and domain verification:

1. Log in to PortPro.

2. Go to Settings > System Generated Emails > Configuration.

3. Enter the preferred sending address (e.g., Contact Name <example@yourdomain.com>).

4. Save changes
   

This completes the custom domain email configuration process.
