Laravel + Layer 9 SMTP

Point Laravel’s mailer at mail.l9s.io with SMTP AUTH and TLS. Send password resets and notifications without local sendmail headaches.

Typical .env values

Use SMTP mailer with host mail.l9s.io, port 587 (STARTTLS) or 465 (TLS), and your Layer 9 credentials from the portal.

Align SPF/DKIM/DMARC for your sending domain before production traffic.

Does Laravel need a special SDK?

No — standard SMTP configuration is enough.
