So the history repeats again, I can’t find one simple plugin that fits my needs, so I created one for myself and share it with you in the hope that you’ll find it useful. If you’re happy with the plugin [please don’t forget to give it a good rating](https://wordpress.org/support/plugin/sar-friendly-smtp/reviews/?filter=5), it will motivate me to keep sharing and improving this plugin (and others). **IMPORTANT:** Support requests must be created using the [Issues tab at the Github repository](https://github.com/samuelaguilera/sar-friendly-smtp/issues) #### karakteristika * KISS principle. * No third-party libraries for SMTP, uses WordPress core. * Respect fields modified by other plugins (e.g. Gravity Forms). * Option to enable debug mode (logs communication between WordPress and your SMTP server in PHP’s error_log file, check [FAQ](https://wordpress.org/plugins/sar-friendly-smtp/faq/) for more details). * Uses WordPress settings API for settings page, making it secure by default. * Custom capability for settings access, so you can allow non administrator users to access to the settings page if you need it using [User Role Editor](https://wordpress.org/plugins/user-role-editor/)( or any other similar plugin). * Send Email Test page. Allowing you to test if WordPress is able to send emails using the SMTP server details provided. * Constants available to override settings using wp-config.php (useful to set same settings network-wide on a multi-site installation). #### Requirements * PHP 7.0 or higher. * WordPress 4.9 or higher. * SMTP server 🙂 It may work with older versions of PHP and WordPress (and it does in fact at the time of writing this), but I don’t support anything older than the versions mentioned above. #### Përdorimi Just install in your WordPress like any other plugin, activate it and fill settings using your SMTP server details. If you’re not sure about what you need to put in each field, ask to your SMTP server support. #### Zhvillues If you want to contribute to the development of this plugin fixing a bug or **suggesting** any improvement, feel free to submit a pull request to this repo. ## Instalim * Extract the zip file and just drop the contents in the `wp-content/plugins/` directory of your WordPress installation (or install it directly from your dashboard) and then activate it from Plugins page. ## PBR ### I can’t receive emails sent by my WordPress, what happen? This plugin is just a way to tell WordPress something like: “Please dear WordPress, use my SMTP server to send the emails, not the web server.” That means that **this plugin doesn’t send you emails**, when the plugin is enabled WordPress sends your emails using **your SMTP server**. If you’re having trouble sending your emails, you can activate the debug mode in settings page. That activates the logging of the commands and data between WordPress and your SMTP server, and **most of the time** you will find useful information in your PHP error_log file. **Remember to turn off Debug Mode when you’re done with the troubleshooting to avoid raising your server load by generating unnecessary logs.** ### Where can I find that PHP error log file? The location of the PHP error_log file it’s not the same in all servers, because it can be customized by the server admin. In all cases you’ll need to use a (S)FTP client to check it. Example of possible locations: * Some major shared hosting companies (i.e Hostgator), put this file in the root of your site (i.e. /public_html/ ) with the name of error_log * Some other shared hostings put it inside of a “logs” directory in the root of your (S)FTP account. * And unfortunatelly, there’re some hosting companies that don’t allow the user to access directly to this error log file. So you’ll need to contact your hosting support. * If you’re using a VPS or dedicated server you know how to find this file! 😉 The path of the file anyway is controled by error_log directive in php.ini or if you’re using PHP-FPM by php_admin_value[error_log] in your pool .conf file. * Where there’s no path specified for the PHP’s error_log file, this information should be added to your web server (i.e. Apache) error log. If you don’t know how to access to that file or you can’t see any useful information about the sending process on that log file, **you need to contact with the support staff of your SMTP server** to ask them for the information. ### I’m using Gmail SMTP server and all my emails are sent with my Gmail account address in the from address field even when I have another email in ‘From Email Address’, why? Gmail/Google Apps (and probably other servers too) only allows you to send emails using your account email address in the FROM header. ### My emails are sent, debug log looks ok, but they’re lost in the cyberspace, never reach the destination! Why life is so cruel with me? I’m going to cry! Be happy man, life is life… Sending an email successfully does not guarantee you that it will reach the destination, an email goes thru many email servers before reaching the recipient email inbox. And finally, if your email reach the server that handles the inbox for the destination email address, it’s this server who has the last word to decide if your email is going to be delivered to the recipient or not. Lots of things can be considered to reject your emails in destination without any notice: Content of the email triggering spam filters (i.e. too many links in your email content) or recipient server policy, bad reputation of your domain or SMTP IP, missing recommendations (i.e. SPF record)… It’s a whole world man! I would recommend you to check any of the services below, all of them provide a SMTP server to use and can help you to improve your email delivery. [Mailgun](https://www.mailgun.com/) [Sendgrid](https://sendgrid.com/) [Mailjet](https://mailjet.com/) [SparkPost](https://www.sparkpost.com/) [Elastic Email](https://elasticemail.com/) [MailRelay](https://mailrelay.com/) [Sendinblue](https://sendinblue.com/) ### What means error messages displayed on send email test screen? SMTP Error: Could not authenticate -> This indicates the server refused your authentication data, probably due to incorrect username or password, but other incorrect settings can cause this too (like a bad port or encryption). Double check you have entered correct information in settings and contact with your SMTP server support if all is ok from your side. SMTP connect() failed -> This indicates WordPress was not able to connect with your SMTP server. Probably you have an error in the hostname, port or encryption settings. This error can happen also if your web hosting is blocking connections to your SMTP host or your SMTP host is blocking your for some reason. ### My emails always have the site name as from name, FROM Name in settings is not being used, why? As you know this plugin is made to be friendly with other plugins that makes changes to the WordPress default settings, respecting changes made by these third-party plugins. Therefore the **FROM Name setting is only used when the email has the default value** for this field: **WordPress** An example of plugin that makes your emails to be sent with the site name is BuddyPress( tested with BP 2.2.1). ### Can I set the SMTP server configuration from wp-config.php using constants? Since version 1.1 you can do this. Below you can see an example of use. ``` define( 'SAR_FSMTP_USER', 'your_username' ); define( 'SAR_FSMTP_PASSWORD', 'your_password' ); define( 'SAR_FSMTP_HOST', 'smtp.example.com' ); // IMPORTANT! Don't use quotes for the SAR_FSMTP_PORT value! define( 'SAR_FSMTP_PORT', 587 ); define( 'SAR_FSMTP_ENCRYPTION', 'tls' ); // These two are optional. SAR_FSMTP_FROM must be a valid email according to is_email() WP core function. define( 'SAR_FSMTP_FROM', 'you@example.com' ); define( 'SAR_FSMTP_FROM_NAME', 'Your Name' ); ``` In 1.2 the following constants are added too: ``` define( 'SAR_FSMTP_DEBUG_MODE', 'error_log' ); define( 'SAR_FSMTP_ALLOW_INVALID_SSL', 'on' ); ``` This is useful if you want to use the same settings network-wide in a WordPress network (multisite installation). ## Shqyrtime ![](https://secure.gravatar.com/avatar/f907f1f08f8347f6cc0b0aa0768c8b5ac47c4c83e2e1e5c91139759173f33245? s=60&d=retro&r=g) ### 󠀁[Simple and Clean](https://wordpress.org/support/topic/simple-and-clean-148/)󠁿 [sayginer](https://profiles.wordpress.org/sayginer/) 13 Korrik, 2024 It is clean and simple plugin.

Just does the job!](https://wordpress.org/support/topic/super-leightweight-just-does-the-job/)󠁿 [mahyulan](https://profiles.wordpress.org/mahyulan/) 22 Prill, 2024 I used to use PostMan SMTP – now Post SMTP plugin, but this has become very annoying. Because it has become a bulky plugin that almost forces you to go to a paid subscription. The Post SMTP zip file is 8,7MB, while this SAR Friendly SMTP is only 38kB! Of course the other plugin has many more options, but if you just need the mail to be sent by SMTP this SAR Friendly SMTP plugin is absolutely fabulous. Therefore I just made a small donation. ![](https://secure.gravatar.com/avatar/e23bc83e4d2021743128c842c81d06b1525766b937c55d86827340d8679448ad? s=60&d=retro&r=g) ### 󠀁[Works fine](https://wordpress.org/support/topic/works-fine-1551/)󠁿 [Qorege](https://profiles.wordpress.org/qored/) 21 Dhjetor, 2023 Thank you! ![](https://secure.gravatar.com/avatar/1aa245415d4c7bd18a53514a87dde2157d36052c2139c07ccdd6532e60776ef4? s=60&d=retro&r=g) ### 󠀁[Perfect!!!](https://wordpress.org/support/topic/perfect-9679/)󠁿 [Joseph](https://profiles.wordpress.org/josephapeke/) 1 Janar, 2023 Perfect and tiny in size…just awesome ![](https://secure.gravatar.com/avatar/a17f85ad3bb3cb91cf3f64c02d6b7e5491dcf27e93281f261c59c86bd556043c? s=60&d=retro&r=g) ### 󠀁[So far, so good! HTML mail at last](https://wordpress.org/support/topic/so-far-so-good-html-mail-at-last/)󠁿 [jschoellen](https://profiles.wordpress.org/jschoellen/) 12 Gusht, 2022 We tried Postmark. We tried Post SMTP. They would either not deliver e-mails at all (via a SendGrid API relay)… or would only relay text versions. With this plugin, it just WORKED. Thank you! ![](https://secure.gravatar.com/avatar/fd477da7af4d36eff91b1e2e3d20f9ff1da226f42a748c16b495ac0242a6dcde? s=60&d=retro&r=g) ### 󠀁[Simple & good, straight action plugin](https://wordpress.org/support/topic/simple-good-straight-action-plugin/)󠁿 [seofreelance](https://profiles.wordpress.org/seofreelance/) 8 Shkurt, 2022 This is just what it needs to be. A few settings, a simple easy way to proof them OK and just care for your server or hosting has everything in place, as the plugin works just great. ¡Gracias Samuel!
