Before you begin#

Before you begin, get the SMTP host and the scheme, port, and authentication requirements from the mail service administrator or provider. Copy any credentials from that provider’s own account settings; do not put secret values in documentation.

Supported transport and settings#

The SMTP profile sends through a remote SMTP server. It supports the standard SMTP and SMTPS transport schemes. Enter the host and any authentication details supplied for the SMTP service you plan to use.

  • Transport schemes: smtp (default) and smtps.
  • Required: SMTP host.
  • Optional: SMTP port (default 587), SMTP username, and SMTP password. The password is a secret field.
  • Raw DSN override: leave empty to build the transport from the profile fields.

For transport background, see Symfony Mailer documentation.

Create the connection#

  1. In WordPress admin, open Jooosi Mail → Connections and choose New connection.
  2. Enter a Connection name.
  3. Select SMTP in Profile.
  4. Choose smtp or smtps in SMTP scheme.
  5. Enter the SMTP host. Set the port, username, and password as required by your SMTP service. The password is stored as a secret.
  6. Leave Raw DSN override empty to use the profile fields.
  7. Review the sender and other connection settings relevant to your setup, then choose Create connection.

See the shared Connect a provider guide for the connection workflow.

Verify delivery#

Follow Send a test email and send a real message to a mailbox you can check. Review the attempt in Jooosi Mail → Logs and confirm that it arrives. The test uses the connection’s current SMTP scheme, host, port, and credentials.

Webhooks#

The built-in SMTP profile does not declare provider webhook support. Review SMTP attempts in Jooosi Mail email logs.

Troubleshooting#

  • If the connection cannot authenticate, compare the selected scheme, host, and port with the values required by your SMTP service. Add a username and password only when the service requires them.
  • If the log records a transport error, use its details to check the remote server’s connection and authentication requirements.
