General Settings

screenshot of SMTP Mailer plugin settings

SMTP Host

Your outgoing mail server which will be used for sending email (e.g. smtp.gmail.com).

SMTP Authentication

Enable/Disable SMTP authentication when sending an email (Supported values: True/False).

SMTP Username

The username to connect to your SMTP server. You will need to provide a username if you enable “SMTP Authentication”.

SMTP Password

The password to connect to your SMTP server. You will need to provide a password if you enable “SMTP Authentication”.

Type of Encryption

The encryption which will be used for sending an email (Supported values: TLS/SSL/No Encryption. TLS is recommended).

SMTP Port

The port which will be used when sending an email (587/465/25). If you choose TLS the port should be set to 587. For SSL use port 465 instead.

From Email Address

The email address which is be used as the From Address if it is not supplied to the mail function.

From Name

The name which will be used as the From Name if it is not supplied to the mail function.

Test Email

“Test Email” menu allows you to test the functionality of the plugin after you have configured everything.

Server Info

“Server Info” menu displays some technical information regarding your server. This is very useful for troubleshooting.

Outgoing Mail Server Configurations

Here are the settings for all the popular outgoing mail (SMTP) servers.

Gmail

SMTP Host: smtp.gmail.com
SMTP Authentication: True
SMTP Username: Either your Gmail account username or full email address
SMTP Password: Your Gmail account’s password
Type of Encryption: TLS or SSL
SMTP Port: 587 (if TLS) or 465 (if SSL)

Troubleshooting

1.For security reasons, Gmail now blocks any incoming connection to its SMTP server. In order to make a connection to the Gmail SMTP server and send email, you will also need to allow less secure apps in your account.

If you do not wish to turn on this feature, you might want to take a look at my Gmail SMTP plugin.

2.When you are sending an email for the first time via SMTP, you might get this SMTP Error: “Could not authenticate“.

In order to fix this issue login to your Gmail account first. You should see a security warning from Gmail upon login – “Your account has been hacked” or “Somebody stole your password”. As soon as you confirm that it was you who tried to login (Just click on the link that shows up in that message), the plugin should be able to connect to the Gmail SMTP server.

Yahoo

SMTP Host: smtp.mail.yahoo.com
SMTP Authentication: True
SMTP Username: Your full Yahoo email address
SMTP Password: Your Yahoo email account’s password
Type of Encryption: TLS or SSL
SMTP Port: 587 (if TLS) or 465 (if SSL)

Outlook

SMTP Host: smtp-mail.outlook.com
SMTP Authentication: True
SMTP Username: Your email address
SMTP Password: Your password
Type of Encryption: TLS
SMTP Port: 25 or 587 (if port 25 is blocked)

SendGrid

SMTP Host: smtp.sendgrid.net
SMTP Authentication: True
SMTP Username: Your SendGrid username
SMTP Password: Your SendGrid password
Type of Encryption: TLS
SMTP Port: 587 (if TLS) or 465 (if SSL). If you select “No Encryption” use port 25 instead.

Mandrill

SMTP Host: smtp.mandrillapp.com
SMTP Authentication: True
SMTP Username: Your Mandrill username
SMTP Password: Your Mandrill password
Type of Encryption: TLS
SMTP Port: 587, 25 or 2525 (if TLS or No Encryption). For SSL use port 465.

If you have any questions feel free to share it in the comment section.

I’ve tried using both Gmail plugin and SMTP-Mailer that you’ve created, and I have also tried several different accounts. I am using Google Apps accounts, and have had it work previously, even fixed security settings on account to “allow” the smtp access…. what am I missing?

I keep getting a whole bunch of error code lines but the last 7 are:
SMTP Error: Could not authenticate. CLIENT -> SERVER: QUIT SMTP -> get_lines(): $data is "" SMTP -> get_lines(): $str is "221 2.0.0 closing connection e20sm14124497oic.19 - gsmtp" SERVER -> CLIENT: 221 2.0.0 closing connection e20sm14124497oic.19 - gsmtp Connection: closed SMTP Error: Could not authenticate.

I’ve tried changing the option to allow for less secure apps but this didn’t make a difference. Can not receive any test emails

  @Richard, Have you logged into your Gmail account after this? You might see a security warning in your account upon login. As soon as you confirm that it was you who tried to login, the plugin should be able to connect to the Gmail SMTP server.
  
  What port combination did you use? Please copy and paste the content from the “Server Info” tab so I can take a look.

I am trying to run the tests from the “Test Email” tab and I am only getting this message:

Great plugin and looks exactly like what I am looking for.
After configuring the plugin I can send the test E-mail successfully (I’m using mailgun.org as SMTP server). However, I get neither new comments nor user registration notifications (or any other E-mails) although the notifications are enabled in the settings of my wordpress. It seems like the wordpress simply doesn’t use this plugin when attempts to send E-mails. Do you have an idea what I am doing wrong?
Here is my server info:
OS: Linux 846098f38250 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64

  @Alex, Have you tried the test email functionality? WordPress uses the wp_mail function to send email. As long as that functon is getting called the plugin should be able to override the default configurations with SMTP.

    If you mean the test E-mail functionality provided by the plugin – then yes, I’ve tried it and it works, I also receive the test E-mail. I’ve tested several other plugins and couldn’t get them to work, even the test E-mail functionality wouldn’t work.
    The only plugin that works for me is Easy WP SMTP, but I am getting HTTP timeouts on POST requests with it (e.g., comments) because the plugin is taking too long to send an E-mail and the HTTP handler wouldn’t return until that operation is finished, so I had to deactivate it.
    I was trying to find a way to debug wordpress to see why the smtp-mailer-plugin can’t deliver E-mails (while test E-mail works!), but couldn’t find a simple way to do that (I’m not very familiar with php). I’m using nginx with fastcgi and have php-fpm log set to ‘warning’ – no errors from smtp-mailer-plugin in there when I’m e.g. posting a comment.
    Could you maybe give me a hint on a way to debug the wordpress/plugin?

      @Alex, If the test email works that means there is nothing wrong with your setup. Test email also uses the wp_mail function to send email. Are you using any CDN like cloudflare? Is your website hosted on a cloud server? Some users were having a similar issue with my Gmail SMTP plugin.

        My wordpress is running in a Docker container on Amazon AWS. I don’t think I have the timeout issue, the Test E-mail is sent very fast, within 1 second. I still suspect there is something wrong with my WP configuration like it tries to use system mail instead of wp_mail, although from you say I understand it’s not possible.
        If it even makes sense, is there a way to make wordpress send me an E-mail other than creating a comment or adding a new user (other than the Test Mail of the plugin)? I have several other plugins, but I don’t see where there could be a collision with smtp-mailer.

        @Alex, I don’t think there is an email functionality in the WordPress admin. Do you want to contact Amazon AWS to see if they have any restrictions on outgoing email? It seems to only happen on the front end.

        I’ve just discovered that the E-mail notification on user profile update (change of password) works. However, the E-mail notification on a new comment still doesn’t. I believe this rules out the hosting or smtp-mailer configuration problem. What else could it be then?
        Double checked the Settings -> Discussion -> Email me whenever … Anyone posts a comment: it’s enabled. Any idea?

I just try to send this here again, to see the error message. I already got a reply via e-mail!

Seems like a great plugin. I just need to make sure I’m setting it up correctly: Is everything I need to do to install it and enter my SMTP details? Or do I also need to tell WordPress in some way to use this plugin instead of the built in way? (It’s a little confusing with the info “Configure the wp_mail() function to use SMTP instead of the PHP mail() function.” because it can be understood as that I as a user need to configure something in WordPress.

And how do I know that the plugin is used rather than the built in way? When I check the source of two e-mails, they look similar to me. They both refer to PHPMailer as the X-Mailer (even in the test e-mail).

Unfortunately Ive tried both your plugins and neither worked to route through GoDaddy to Gmail. Unable to send any emails from website that is host3ed with GoDaddy if email is at gmail. SHAME ON YOU GODADDY!

Hello.
I keep receiving this message using TLS at port 587:
Warning: stream_socket_enable_crypto(): Peer certificate CN=`XXXXXXXX’ did not match expected CN=`YYYYYYYY’

I’m using a valid certificate. Its a shared whm environment with Centos 7 + php 5.6.
PS: Without encryption it works fine but my customer wants to use TLS

  @Willrich, Your SSL certificate on the server may not be configured correctly. Did you try checking this option “Disable SSL Certificate Verification”?

    Was a problem with the SMTP provider using custom configuration. Thanks for your reply. 🙂

  @ava, There is a thread on this topic here: https://github.com/PHPMailer/PHPMailer/issues/179.
  
  It looks like a DNS configuration issue.
