two things i don't like about Xampp on Linux

1) There is no zip download as far as i can see, so you have to download a "run file" and run an install; so there is no way to navigate files without runing the installer.
2) Its an embbed system, so edits to native php.ini will have no affect.

Anyway you have to find xampp own version of php.ini and edit that.

I think there may be a sendmail.ini where you set up ports. eg smtp_port=587

I'm going to give you an alternative PHPMailer https://packagist.org/packages/phpmailer/phpmailer


What i like about PHPMailer is that it works from a website which is being developed from localhost context. So you can get it working while developing ,set up using gmail as i did if you want etc before going live

1) https://sourceforge.net/projects/xampp/f...ws/8.1.10/  << Allows me to download .zip?
2) Windows:   c:\xampp\php\php.ini        Linux: /opt/lamp/etc/php.ini

My answer:
-----------------------
CodeIgniter 4 allows you to set SMTP credentials, within  App/Config/Email.php or through the .env file.
The build-in core class has multiple solutions to debug and modify it's settings, it doesn't require additional packages that basicly does the same.

Also check error.log and debug.log in sendmail folder.

If your on Windows and you must use CodeIgniter 4 Email Class then you can use this tool, It's what I use for testing.
