Send emails from Laravel through mySMTP

Laravel’s built-in mail system supports SMTP out of the box. Point it to mySMTP by editing your environment file and clearing the configuration cache.

Prerequisites

A Laravel application
Your mySMTP credentials (see Setting up SMTP credentials)
A verified sending domain

SMTP settings

Setting	Value
Host	`relayxx.mysmtp.com` (from your setup email)
Host (shared IP, DK only)	`mail.mysmtp.com`
Port	`587`
Encryption	TLS (STARTTLS)
Username	Your mySMTP SMTP username
Password	Your mySMTP SMTP password

Shared IP plans are only available to customers in Denmark.

Configure Laravel SMTP

Update .env

Open .env in the root of your Laravel project and set the mail variables. Use the version-specific encryption setting:

MAIL_MAILER=smtp
MAIL_HOST=relayxx.mysmtp.com
MAIL_PORT=587
MAIL_USERNAME=your-mysmtp-username
MAIL_PASSWORD=your-mysmtp-password
MAIL_FROM_ADDRESS="noreply@yourdomain.com"
MAIL_FROM_NAME="Your App Name"

For Laravel 11 and later, set MAIL_SCHEME=tls instead of MAIL_ENCRYPTION:

MAIL_SCHEME=tls

For Laravel 10 and earlier, set:

MAIL_ENCRYPTION=tls

Clear config cache

Run the following command so Laravel picks up the new values:

php artisan config:clear

Send a test email with Tinker

Start Tinker:

php artisan tinker

Then run:

Mail::raw('This is a test email from Laravel through mySMTP.', function ($message) {
    $message->to('your-email@example.com')
            ->subject('mySMTP Test');
});

Check your inbox for the message.

Do not commit .env files with real passwords to version control. Load credentials from environment variables, or use Laravel’s encrypted environment files (Laravel 11+) when possible.

Troubleshooting

Connection refused or timeout

Make sure you are using your real mySMTP hostname (not relayxx.mysmtp.com). Check that your server allows outbound connections on port 587. If the port is blocked, try 2525 or 465.

Authentication failed

Re-enter your mySMTP username and password in .env, then run php artisan config:clear again. Verify there are no extra spaces or quotes.

Emails go to spam

Verify SPF, DKIM, and DMARC are configured for your sending domain. See DNS settings quick explainer and SPF, DKIM, DMARC, and BIMI explained.

Run the Sender Readiness Checklist and Email Header Analyzer in the mySMTP Deliverability Toolbox.

Test email does not arrive

Check your Laravel logs (storage/logs/laravel.log) for SMTP error details. Also confirm MAIL_FROM_ADDRESS uses a domain authenticated with mySMTP.
