How to Fix Email Forwarding Failures Using SRS

As of January 2026, Google has retired the "Check mail from other accounts" POP3 feature for Gmail. This means the service no longer supports pulling emails from external providers via POP3. Moving forward, setting up email forwarding is the primary way to manage a custom domain through the Gmail web interface.

Note: This guide assumes you already have your DKIM and DMARC records properly configured for your domain.

The Problem

For custom domain names, standard email forwarding often breaks SPF (Sender Policy Framework) checks because the forwarding server is not an authorized sender for the original domain.

Types of Tests

Before we get back to concrete examples there are a few terms we'll want to define: State Verification, Behavior Verification, Solitary Unit Test, and Sociable Unit Test. These terms have plenty of definitions available on the Internet; unfortunately, many of those definitions differ and some are in direct conflict. This chapter will define those terms for the context of this book.

Unit Test

The definition of Unit Test is quite general:

In computer programming, unit testing is a method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures are tested to determine if they are fit for use. [...] A unit could be an entire module, but it is more commonly an individual function or procedure. --Wikipedia
