如何配置邮箱的SMTP?
Once you’ve selected Other SMTP as your mailer, a new section will appear with additional SMTP settings for you to configure.
- SMTP Host: The outgoing server listed in your email provider’s SMTP settings.
- Encryption: The type of encryption used for the SMTP connection (TLS, SSL, or none).
- SMTP Port: The port your provider uses for SMTP connections.
- Authentication: Turns authentication on or off. Most providers require it to be on.
- SMTP Username: Your email address.
- SMTP Password: You’ll need to generate an app password for your account, as detailed later in this tutorial.
Each email provider requires slightly different SMTP configurations. We’ve compiled a list of SMTP configurations for popular email providers below if you’re not sure what to enter for these settings.

Generating an App Password
To use SMTP on your WordPress site, you’ll most likely need to generate an app password in your email account. Below, we’ll show you how to do this for Gmail, Yahoo, AOL, Hotmail, and Live.
Generating an App Password in Gmail
Note: Before you can generate an app password in Gmail, you’ll need to turn on Google’s 2-Step Verification.
To create an app password in Gmail, log in to your Gmail or Google Workspace account.
Then, go to App passwords in your security settings. On this page, click on the Select app dropdown.
Next, select the Other (Custom name) option from the dropdown menu.
Then, enter WP Mail SMTP in the field provided and click the blue GENERATE button.
This will generate an app password that you can use for your WP Mail SMTP setup.
You’ll want to copy this password, then return to your WP Mail SMTP settings in your WordPress dashboard. From here, paste the password into the SMTP Password field and save your settings.
Note: Sometimes Gmail may automatically block the sign-in used by SMTP for security reasons, even when using an app password. When this happens, an email will be sent to your recovery email address with a sign-in attempt warning (see below).
To remove this block, you’ll need to click the Check Activity button in the email (or visit your account’s Notifications page) and follow the instructions provided to let Google know this was a legitimate login attempt.
Generating an App Password in Yahoo
Note: For Yahoo Business (Verizon Small Business Essentials), please see the official documentation on managing app passwords for steps on finding the proper settings for generating your app password. Then you can follow the rest of the steps below.
First, log in to your Yahoo account. Then open your account’s security settings.
In your account’s settings, you’ll need to generate a special password for your WP Mail SMTP integration. To do so, click on Generate app password.
This will open up an overlay, where you’ll need to select the app you’ll be granting permission to. From the dropdown, select the Other option and enter WP Mail SMTP in the field provided. Then click the Generate button.
This will generate a one-time password that you can use with WP Mail SMTP.
Copy this password, then go back to your WP Mail SMTP settings in your WordPress dashboard. Paste the password into the SMTP Password field and save your settings.
Generating an App Password in AOL
To generate an app password in AOL, log in to your account. Then open your security settings.
You’ll need to generate a special password for your site’s WP Mail SMTP integration in your account’s settings. To do so, click on Generate app password.
This will open up an overlay, where you’ll need to select the app you’ll be granting permission to. From the dropdown, choose the Other option and enter WP Mail SMTP in the field provided. Then click the Generate button.
This will generate a one-time password that you can use with WP Mail SMTP.
Copy the password, then return to your WP Mail SMTP settings in your WordPress dashboard. Paste the password into the SMTP Password field and save your settings.
Generating an App Password in Outlook
To create an app password in Outlook (including Live and Hotmail accounts), you’ll first need to log in to your account. Then open your account’s security settings.
From here, select the Advanced security options to open up additional security settings.
Next, you’ll need to activate 2-Factor Authentication (2FA) for your account, if you haven’t already.
Once you’ve enabled 2FA for your account, you’ll return to the Security page, where you’ll need to generate an app password to use with WP Mail SMTP.
To generate your app password, scroll to the App passwords section and click on Create a new app password.
This will generate a random password that you can use for your account.
Copy the password, then go back to your WordPress dashboard and WP Mail SMTP settings. Paste the password into the SMTP Password field and save your changes.
Generating an App Password in Zoho
To generate an app password for Zoho, you’ll first need to log in to your account.
Once you’re logged in, head to your account’s security settings.
From here, scroll to the Application-Specific Passwords section and click the Generate New Password button.
In the field that pops up, enter WP Mail SMTP and click the Generate button.
Next, copy the password that Zoho has generated for you.
Then, head over to your WP Mail SMTP settings. Be sure to paste this password into the SMTP Password field and save your settings.
Sending a Test Email
Now that all of your SMTP settings are in place, the next step is to make sure everything is working correctly. To do so, go to WP Mail SMTP » Tools and click on the Email Test tab.
In the Send To field, you can enter any email address whose inbox you have access to. We recommend leaving the HTML setting ON unless you know you’ll only be sending plain text emails.
After you’ve filled out the required settings, go ahead and click the Send Email button to send your test email.
Once the test email has been sent, you should see a success message that reads, “Success! Test HTML email was sent successfully! Please check your inbox to make sure it was delivered.”
If you check the inbox for the email address you entered, you should see the email for this test.
Note: If you’re using a Yahoo email address, it may take 5–10 minutes for emails to arrive in your inbox (including test emails).
Note: If you have forms that send emails through your site, be sure to also test these out by submitting a couple of test entries. That way, you can be certain that these SMTP settings apply to your form emails as well.
Frequently Asked Questions
Why am I getting the following error?
SMTP Error: Could not authenticate
In the sections below, we’ll go over some of the causes of this issue, and a few courses of action you can take to fix it:
Incorrect SMTP Username and Password
In your WP Mail SMTP settings, double-check that your SMTP Username and SMTP Password are correct.
Note: The following mailers require you to generate an app-specific password: Gmail, Hotmail or Live, Yahoo, Yahoo Business, and AOL. For details on how to generate passwords for each of these apps, please refer to the Generating an App Password section.
Misplaced Constants
If you are using constants to set up WP Mail SMTP, please double-check to be sure you’ve added them in the correct place. Please refer to our guide on securing SMTP settings with constants for more details.
Adding a Custom Filter
The WordPress (PHPMailer) uses these auth types in order:
CRAM-MD5, LOGIN, PLAIN, XOAUTH2
If the receiving SMTP server is not configured correctly, it will fail at the first one.
If you’ve covered the two troubleshooting options above, and you’re still receiving the error, you can try adding the following filter:
add_filter( 'wp_mail_smtp_custom_options', function( $phpmailer ) {
$phpmailer->AuthType = 'LOGIN';
return $phpmailer;
} );
Note: For extra guidance, please see WPBeginner’s tutorial on adding custom code.
That’s it! You’ve now configured the Other SMTP mailer on your WordPress site, and your site’s emails should start delivering successfully and reliably.
Next, would you like to keep a record of all the emails sent out from your WordPress site? Be sure to check out our doc on setting up email logging so you can always see what emails have been sent.
