WP Mail SMTP by WPForms

Description

This plugin reconfigures the wp_mail() function to use SMTP instead of mail() and creates an options page that allows you to specify various options.

You can set the following options:

  • Specify the from name and email address for outgoing email.
  • Choose to send mail by SMTP or PHP’s mail() function.
  • Specify an SMTP host (defaults to localhost).
  • Specify an SMTP port (defaults to 25).
  • Choose SSL / TLS encryption (not the same as STARTTLS).
  • Choose to use SMTP authentication or not (defaults to not).
  • Specify an SMTP username and password.

WP Mail SMTP plugin works with all major email services such as Gmail, Yahoo, Outlook, Microsoft Live, and any other email sending service that offers SMTP.

Why WP Mail SMTP

The goal of WP Mail SMTP plugin is to help fix the common “WordPress not sending an email issue”.

Often times an email sent out by your WordPress site either lands in the spam folder or get completely rejected by popular email providers.

My plugin still sends mail via the mail() function

If other plugins you’re using are not coded to use the wp_mail() function but instead call PHP’s mail() function directly, they will bypass the settings of this plugin. Normally, you can edit the other plugins and simply replace the mail( calls with wp_mail( (just adding wp_ in front) and this will work. I’ve tested this on a couple of plugins and it works, but it may not work on all plugins.

Will this plugin work with WordPress versions less than 2.7?

No. WordPress 2.7 changed the way options were updated, so the options page will only work on 2.7 or later.

Can I use this plugin to send email via Gmail / Google Apps

Yes. Use these settings:
Mailer: SMTP
SMTP Host: smtp.gmail.com
SMTP Port: 465
Encryption: SSL
Authentication: Yes
Username: your full gmail address
Password: your mail password

Can you add feature x, y or z to the plugin?

Short answer: maybe.

By all means please contact us to discuss features or options you’d like to see added to the plugin. We can’t guarantee to add all of them, but we will consider all sensible requests. We can be contacted here:

Reviews

Does not work

Installed and the plugin does not work at all. Test email said it was successful (both with and without authentication) and was never received (checked spam etc).

Seems to do absolutely nothing.
