Sending SMTP Mails with SilverStripe 4

Since SilverStripe 4 uses Swift Mailer for sending emails, you can easily activate SMTP support for it.

You just need to setup a project's email config file, e.g. mysite/_config/email.yml.

Using gmail as example, a configuration would look like:

---
Name: myemailconfig
After: emailconfig
Only:
  environment: 'live'
---
SilverStripe\Core\Injector\Injector:
  Swift_Transport:
    class: Swift_SmtpTransport
    properties:
      Host: smtp.gmail.com
      Port: 587
      Encryption: tls
    calls:
      Username: [ setUsername, ['[email protected]'] ]
      Password: [ setPassword, ['`EMAIL_SMTP_PASSWORD`'] ]
      AuthMode: [ setAuthMode, ['login'] ]

The password is configured here through EMAIL_SMTP_PASSWORD, which will be defined in your .env file:

SS_DATABASE_CLASS="MySQLPDODatabase"
SS_ENVIRONMENT_TYPE="live"
SS_DATABASE_SERVER="…"
SS_DATABASE_USERNAME="…"
SS_DATABASE_PASSWORD="…"
SS_DATABASE_NAME="…"

EMAIL_SMTP_PASSWORD="…"

SilverStripe sends now emails via SMTP and gmail.

Note: I updated the article on 17th May 2018 using a better way to descripe smtp usage.
