Send mails throught SMTP server. Simplest option to send mail when hosting or server do not permits send mail or is missconfigured.
We also could to check the SMTP options and check the native PHP mail.

== Installation ==
1 - CL Simplest SMTP can be installed directly through your WordPress Plugins dashboard.
2 - Click "Add New" and Search for "CL Simplest SMTP"
3 - Install and Activate

== Frequently Asked Questions ==
### This plugin adds any options to my database?
If you configure the plugin with constants in your `wp-config.php` file (see next FAQ), this plugin does not add any data to your database. This is the fastest option because the mail does not need to check data from your database.

If you configure the options from the WordPress admin panel, the plugin will save only one array of options in your database with all the SMTP parameters. The options array saved in your database (`wp_options` table) is `cl_simplest_smtp_options`.

### Configure plugin with constants.
Configure plugin with constants is the fastest option and also avoids database queries.

We must set these constants in our `wp-config.php` file:

`define( 'CL_SIMPLEST_SMTP_HOST', 'your-smtp-host' );` // SMTP server
`define( 'CL_SIMPLEST_SMTP_AUTH', true );` // enable SMTP authentication
`define( 'CL_SIMPLEST_SMTP_PORT', 587 );` // set the SMTP port
`define( 'CL_SIMPLEST_SMTP_USER', 'your-smtp@user' );` // SMTP account username
`define( 'CL_SIMPLEST_SMTP_PASS', 'your-smtp-password' );` // SMTP account password
`define( 'CL_SIMPLEST_SMTP_SECURE', 'tls' );` // To use STARTTLS: 'tls'; To use SSL: 'ssl';
`define( 'CL_SIMPLEST_SMTP_FROM', 'your-smtp-sender@email' );` // SMTP from email
`define( 'CL_SIMPLEST_SMTP_NAME', 'Your Sender Name' );` // SMTP from name

This option is the optimal for security.

### This plugin will slow down my WordPress?
No. This plugin is very lightweight and only adds one CSS file and one JS file if you are in the WordPress SMTP options page `/wp-admin/options-general.php?page=cl-simplest-smtp` and does not add anything to any other pages or on the frontend.

Only adds one database option (first FAQ) with an array of 8 short values and nothing if you configure it with constants in your `wp-config.php` file (the best option for speed and security).

### Can I hide the "Invite me to a coffe" button?
Yes, of course. You must to define the constant `CL_SIMPLEST_SMTP_HIDE_DONATE` as `true`in your `wp-config.php` file and the button will fly out ;)

`define( 'CL_SIMPLEST_SMTP_HIDE_DONATE', true );`

But you can invite me to that coffee at any time from <https://www.paypal.com/donate/?hosted_button_id=V6U6ZLFHNE6N4>

### Can I change the log file name?
Yes, the default mail log file name is `cl-simplest-smtp-log.txt` and is located in `uploads` folder. You can't change the location, but you can change the file name if you define the constant `CL_SIMPLEST_SMTP_LOG_FILENAME` with the file name at your `wp-config.php` file.

Example:

`define( 'CL_SIMPLEST_SMTP_LOG_FILENAME', 'my-cl-simplest-smtp-log-dec-2025.txt' );`

Keep in mind that if the default log file was previously created, it won't be deleted, only the new file will be created and the file that will be deleted on plugin uninstall will be the new defined file.
