Email settings

MAIL_DRIVER=smtp
MAIL_HOST=secure251.inmotionhosting.com
MAIL_PORT=465
[email protected] // your full email address
MAIL_PASSWORD=password // your password
MAIL_ENCRYPTION=ssl
[email protected] // your full email address
MAIL_FROM_NAME=Your name

In other words, set up everything using the "outgoing" settings. Your laravel app will only be sending email out, not receiving.

My .env is configured as suggested here, but I receive an error that I cannot resolve or find any assistance for online:

Class 'Swift_StreamFilters_StringReplacementFilter' not found 

When I comment out my mail code, everything works (contact info inserted into DB). What fails is emailing the data from the form saved like this:

$data = Contact::create($validatedAttributes);

Attempting to mail:

Mail::to(request('email'))
                ->send(new ContactForm($data));

The mailable instance:

class ContactForm extends Mailable
{
    use Queueable, SerializesModels;

    public $data;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct($data)
    {
        $this->data = $data;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->markdown('emails.contact-form');
    }
}

The markdown template:

@component('mail::message')
# You received a contact form submission from {{ $data->first_name }}.

Here are the details: 
- Name: {{ $data->first_name }} {{ $data->last_name }}
- Email: {{ $data->email }}
- Message: {{ $data->message }}


Thanks,<br>
{{ config('app.name') }}
@endcomponent

Everything works in MailTrap but not on the server at InMotion Hosting. Any ideas on what I'm doing wrong?
