This article will help you to understand the problem, identify the common causes, and provide a few effective solutions to fix it.
What is a Gmail Delivery Failure?
Gmail delivery failure is an issue that occurs when your sending emails to a Gmail account end up in failure. It usually occurs due to some kind of configuration issue, wrong credentials, or an error in the server. To solve the issue, you should first identify and understand the cause of the problem.
What causes Delivery Failure?
There are multiple factors that can cause delivery failure in Gmail. Some of the common causes are:
- Incorrect server configuration
- Invalid credentials
- Inadequate SMTP setup
- Protocol issues
- SPF or DKIM record issues
- Blacklisting of mail server
How to Fix a Permanent Delivery Failure?
The best way to fix a permanent delivery failure in Gmail is by troubleshooting the issue and resolving the root cause that’s causing the problem. Here are a few steps to get started:
Step 1: Check Server Configuration
The most common cause of delivery failures is configuration related. So, the first step is to check the server configuration and make sure that it is entered correctly in the email client.
Step 2: Validate Credentials
Email credentials, such as email address and password, should be entered correctly and checked for typos to ensure that the delivery issues are not caused due to the wrong credentials.
Step 3: Validate SMTP Setup
The Simple Mail Transfer Protocol (SMTP) is used to send emails. So, you should make sure that the SMTP setup is correct and the system is able to communicate with the mail server.
Step 4: Check DNS Entries
The Domain Name System (DNS) ensures that the emails are delivered quickly by the mail server. If there are any DNS errors or connection issues, it will cause a delivery failure. So, you should check your DNS entries and make sure that everything is correct.
Step 5: Check for SPF and DKIM Records
SPF and DKIM records are used to verify the validity of emails sent from a domain. Make sure that these records are entered in the DNS as expected and not making any delivery errors.
Step 6: Check for Mail Server Blacklisting
Finally, you should check if your mail server is listed on any of the public blacklists. If it is, then you need to contact the blacklist owner to remove it from the list.
