(Copied from MDL-79664 and extended a bit)

Setup outgoing E-Mail

1. For easier testing setup Mailpit (or Mailcatcher, MailHog, ...)

   docker run -d -e MP_SMTP_AUTH_ACCEPT_ANY=true --name=mailpit -p 8025:8025 -p 1025:1025 axllent/mailpit

2. You can find all test mails in the web interface at localhost:8025
3. As an admin, go to Site Administration > Server > Email > Outgoing mail configuration
4. With the above Mailpit running set the following fields:
   • SMTP hosts: "localhost:1025"
   • SMTP username: "username"
   • SMTP password: "password"
   • No-reply address: "noreply@moodle.com"

Test third-party libraries

1. As an admin, go to Site Administration > Development > Third-party libraries.
2. Verify that the library "PHPMailer" is at version 6.9.3.

Test outgoing Mailing

1. Create some users
2. Do some actions that result in the sending of emails to the users:
   • Forgot password
   • Forum notifications (use an announcements forum)
   • Messaging
3. Confirm emails are received by the intended recipients

Code verified against automated checks.
