Configure an SMTP gateway to allow sending email without authentication


Since the SMTP gateway allows sending email without the need to specify a user name and passwords, the user and password should be set to null.

Please replace the mail section in your tower.yml with the following:

    host: ${TOWER_SMTP_HOST}
    port: ${TOWER_SMTP_PORT}
    user: null
    password: null
    auth: false
      enable: false
      required: false

Unable to receive emails for TOWER_CONTACT_EMAIL#

This error occurs due to organizational security policies for email.

The solution below applies if you've setup the SMTP server correctly and the emails are being sent correctly via Tower, but they are rejected by your organizational email ID.


You need to setup/configure the spf, dkim and dmarc for your domain.

For further assistance, please contact your IT staff.
