Configuring Sending Emails

Dex sends emails to a during the registration process to verify an email address belongs to the person signing up. Currently Dex supports two ways of sending emails, and has a third option for use during development.

Configuration of the email provider in Dex is provided through a JSON file. All email providers have a type and id field as well as some additional provider specific fields.

SMTP

If using SMTP the type field must be set to smtp. Additionally both host and port are required. If you wish to use SMTP plain auth, then set auth to plain and specify your username and password.

{
    "type": "smtp",
    "host": "smtp.example.org",
    "port": 587,
    "auth": "plain",
    "username": "postmaster@example.org",
    "password": "foo"
}

Mailgun

If using Mailgun the type field must be set to mailgun. Additionally privateAPIKey, publicAPIKey, and domain are required.

{
    "type": "mailgun",
    "privateAPIKey": "key-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "publicAPIKey": "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY",
    "domain": "sandboxZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ.mailgun.org"
}

Dev

The fake emailer should only be used in development. The fake emailer prints emails to stdout rather than sending any email. If using the fake emailer the type field must be set to fake.

{
    "type": "fake"
}
