SMTP error 530

SMTP is responsible for sending emails. If an email is not sent, it gives error messages with codes. This helps in easy troubleshooting.

An SMTP error code is of a 3 digit format, with each digit has a specific meaning. One such error that shows up while sending an email is ‘SMTP error 530’.

Usually, this is an authentication problem. The basic reasons for this are invalid login details, blacklisted sender IP and so on.

Let’s discuss how our Support Engineers fix this error for our customers.

How we fix the SMTP error 530?

SMTP errors have clearly defined error codes. But, finding the reasons for some errors are tricky. Our Dedicated Engineers, with expertise over a decade in Email services, are skilful in fixing such SMTP errors for our customers.

Now, let’s see the possible causes and fixes for the authentication error.

1. Authenticate the email client

The most obvious reason for SMTP error 530 is not authenticating the Email client properly. This usually happens when the user is unaware of the setting of a new Email client.

For instance, email client authentication in Microsoft Outlook is as follows:

• First select File>> Account Settings.
• Click the Email tab and select the email address.
• Next, click on the More Settings.
• Now, Internet E-mail Settings appear.
• Click on the tab Outgoing Server and enter the details.
• Finally, click the checkbox ‘My outgoing server (SMTP) requires authentication’.

Our Support Engineers provide a detailed guide about authentication for each Email client.

2. Invalid Login credentials

Similarly, invalid or incorrect login details result in this SMTP error. Some customers enter invalid email address and email clients show error 530.

In such situations, our Support Engineers ask the customers to double-check login credentials. We handhold the customers to configure their mail clients without errors.

We also make sure that the recipient’s email address is valid.

3. Blacklisted Sender IP

Another reason that can cause SMTP error is blacklisting of IP by recipient server. The sender IP address may have got blacklisted somehow. If the sender uses this server to send mails, then it shows error 530.

In this case, we check if the recipient server has blocked the sender IP. So, we request them to unban or whitelist it.

4. ISP blocking port

The default SMTP port is 25. But if the customer’s ISP blocks access to this SMTP port, error 530 can occur. This is usually done as a measure to avoid spamming.

A workaround we do is to configure SMTP to use alternate port and enable this port in the mail client settings to send mail via Outlook, Thunderbird etc.

Conclusion

In short, SMTP Error 530 is an authentication error. Usually, this error indicates an unauthenticated email client. Other reasons for this error are blacklisting of sender IP or invalid email address. Today, we saw how our Support Engineers fix this error for our customers.

That is slightly odd. I recommend turning up debug output as more authentication details are shown at SMTPDebug = 4.

One minor thing — don’t set $this->mail->Mailer = 'smtp'; yourself; you’re already calling $this->mail->isSMTP(); which does that for you.

I recommend you avoid $this->mail->SingleTo = true;; it’s deprecated, and you should be sending messages individually yourself.

**I tried everything, but it still failed. Do you have any way to help me?
