To set up the SMTP server for mailing in the Ory Kratos configuration, you need to modify the

config.yml

file. Here are the steps: 1. If your SMTP server enforces certificate-based authentication, configure the client certificate and client private key to use to connect to the server. The files must contain PEM encoded data. Here is an example of how to do this:

yaml # kratos -c path/to/my/kratos/config.yml serve   courier:    smtp:    client_cert_path: /somepath/client.cert    client_key_path: /somepath/client.key

[Source](https://www.ory.sh/docs/kratos/self-hosted/mail-courier-selfhosted#certificate-based-authentication) 2. If your SMTP server requires a unique identifier for the HELO/EHLO command, configure the identifier. The identifier should usually be the domain name of the sending host. If the identifier is not configured,

localhost

is used per default. Here is an example:

yaml courier:    smtp:    local_name: <http://example.org|example.org>

[Source](https://www.ory.sh/docs/kratos/self-hosted/mail-courier-selfhosted#custom-smtp-heloehlo-identifier) 3. You can also configure custom SMTP headers. For example, if integrating with AWS SES SMTP interface, the headers can be configured for cross-account sending:

yaml # kratos -c path/to/my/kratos/config.yml serve   courier:    smtp:    headers:    X-SES-SOURCE-ARN: arn:aws:ses:us-west-2:123456789012:identity/example.com    X-SES-FROM-ARN: arn:aws:ses:us-west-2:123456789012:identity/example.com    X-SES-RETURN-PATH-ARN: arn:aws:ses:us-west-2:123456789012:identity/example.com

To send emails from your server, follow these steps to configure Ory to use a custom SMTP server: - Sign in to the [Ory Console](https://console.ory.sh/projects/current/email-configuration) and go to Customize → Email Configuration. Toggle the Advanced Settings switch and provide the configuration for your SMTP server. - Download the Ory Identities config from your project and save it to a file:

bash ## List all available projects   ory list projects      ## Get config   ory get identity-config {project-id} --format yaml > identity-config.yaml

- Add the configuration for your custom SMTP server:

yaml courier:    smtp:    connection_uri: <smtp://username:password@server:port/>    from_address: [email protected]    from_name: My Company

- Update the Ory Identities configuration using the file you worked with:

bash ory update identity-config {project-id} --file updated_config.yaml

Yes, you can use an SMTP server and specify the port number in the Ory Kratos configuration. The SMTP server and port number are specified in the

connection_uri

field in the configuration file. Here is an example:

yaml courier:    smtp:    connection_uri: <smtp://username:password@server:port/>

In this example, replace

username

,

password

,

server

, and

port

with your actual SMTP server details. The

username

and

password

are your SMTP server credentials,

server

is your SMTP server address, and

port

is the port number your SMTP server is listening on. For example, if you are using Mailgun, your

connection_uri

might look like this:

yaml connection_uri: <smtp://some-user%40mailgun.example.org:[email> protected]:587

Sure, here is an example of how you can set up an SMTP server with a port number in the Ory Kratos configuration:

yaml courier:    smtp:    connection_uri: <smtp://myusername:mypassword@smtp.example.com:587/>    from_address: [email protected]    from_name: My Company

In this example: -

myusername

and

mypassword

are your SMTP server credentials. -

<http://smtp.example.com|smtp.example.com>

is your SMTP server address. -

587

is the port number your SMTP server is listening on. -

[email protected]

is the email address that will appear as the sender of the emails. -

My Company

is the name that will appear as the sender of the emails. Please replace the placeholders with your actual data. [Source](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp)

The

from_address

is the email address that will appear as the sender of the emails. Here is an example:

yaml courier:    smtp:    from_address: [email protected]

In this example,

[email protected]

is the email address that will appear as the sender of the emails. You should replace

[email protected]

with your actual email address. [Source](https://www.ory.sh/docs/kratos/emails-sms/sending-emails-smtp)
