Quick PHP/Laravel Fix: Update Mail.php Configuration for Akaunting Platform

am looking for an experienced PHP developer with knowledge of the Laravel/Akaunting framework to perform a quick configuration update on my live environment.

The Problem:
Our web host support team confirmed that the SMTP EHLO connection is passing the localhost configuration instead of the actual mail server hostname, causing delivery issues.

Scope of Work:
You will need to update the mail configuration file to explicitly fall back to our mail server hostname/IP. The specific steps required are:

Create a backup copy of Config/Mail.php.

Edit Config/Mail.php to update the local_domain line.

From: 'local_domain' => env('MAIL_EHLO_DOMAIN'),

To: 'local_domain' => env('MAIL_EHLO_DOMAIN', '[Our Server Hostname/IP]'),

Save the changes.

Clear the application cache via SSH using Artisan commands:

php artisan config:clear

php artisan cache:clear

Requirements:
Strong experience with PHP and Laravel environments (Akaunting experience is a huge plus).

Comfortable working with SSH / command line to clear application cache.

Fast turnaround time (this is a 10-15 minute task for someone who knows what they are doing).
