Migrating to SMTP API from SMTP Server Solution (legacy)

Paubox SMTP API replaces our legacy solution for sending HIPAA compliant email via SMTP Server. If you are a Paubox legacy SMTP Server customer, here's how you migrate to the new platform.

If you are using SMTP Server Solution (legacy), your SMTP settings likely look something like this:

  • SMTP server host: api.paubox.com
  • Username: <username>@api.paubox.com
  • Password: <password>
  • Port: 587

 

To migrate to SMTP API, follow these steps:

  1. Generate a new API key in the Paubox Dashboard
  2. Update your app's SMTP settings using the following credentials:
    1. SMTP server host: smtp.paubox.com
    2. Port number: 25, 465, or 587 supported (unencrypted connections not accepted)
    3. Username: apikey
    4. Password: <your API key>
