Email via SMTP (mail-smtp)

Delivers the emails your app sends through any SMTP server (Amazon SES, Postmark, Mailgun, your own) with Nodemailer.

Shell

npx calm add mail-smtp

Adds
Files	`app/blocks/mail-smtp/index.js`
Dependency	`nodemailer`
Environment	`SMTP_URL=smtps://user:password@smtp.example.com:465`, `MAIL_FROM=My App <no-reply@example.com>`

Set SMTP_URL to your server (smtp:// or smtps://, credentials URL-encoded) and MAIL_FROM to the sender. MAIL_FROM takes precedence over mail.from in calm.config.js.

INI

SMTP_URL=smtps://AKIA...:secret@email-smtp.eu-west-1.amazonaws.com:465
MAIL_FROM=My App <no-reply@example.com>

While SMTP_URL is empty or still the smtp.example.com placeholder, the block stays inactive: emails go to the devtools Mail panel in development, and calm doctor reports an error in production. The connection is closed on shutdown.

Send email with app.mailer.send({ to, subject, text, html }), exactly as with mail-resend.
