RFC 2822, 3.6.2 error only in produciton when for emails following "abc@xyz.co.uk​" format using Laravel

I have RFC 2822, 3.6.2 error thrown only in production for email addresses which follow this format: abc@xyz.co.uk​

Source code is as follow:

Mail::to($emailAddress, $name)->send($email);

Other email format that pass the Laravel validation works just fine.

I can not reproduce this issue locally

I'm using laravel 5.3

Local: Windows 10 + homestead + mailtrap

Production: AWS + forge + mailgun
