Joomla + MailKite

Joomla is a powerful open-source CMS used by millions of sites. Point its SMTP at MailKite and every notification, user registration, and contact form goes out over your own DKIM-signed domain.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
Joomla with SMTP configured in Global Configuration

Configure SMTP

Open your Joomla admin panel and navigate to System → Global Configuration → Server. Under the Mail Settings section, set the following values.

SMTP Host	`smtp.mailkite.dev`
SMTP Port	`587`
Encryption	TLS (STARTTLS)
Username	`mailkite`
Password	Your API key (`mk_live_…`)
From Address	`hello@yourdomain.com` (on a verified domain)

Global Configuration → Mail Settings

# Global Configuration → Server → Mail Settings

Send Mail:              Yes
Mailer:                 SMTP
SMTP Authentication:    Yes
SMTP Security:          TLS
SMTP Port:              587
SMTP Host:              smtp.mailkite.dev
SMTP Username:          mailkite
SMTP Password:          mk_live_...
From Email:             hello@yourdomain.com
From Name:              Your Site

Test it

Create a test user account or use the contact form on your Joomla site to trigger an outgoing email. Check your MailKite dashboard to confirm the message was relayed successfully.

Troubleshooting

Emails not sending — confirm the From address is on a verified domain.
535 Authentication failed — your password must be your mk_live_… API key, not a separate SMTP password.
Mailer setting — ensure Mailer is set to SMTP, not PHP Mail or Sendmail.
Send Mail disabled — check that Send Mail is set to Yes under Global Configuration → Server.
