Access needed:<\/strong> Site email-settings permission; server access for global relay settings.<\/p>\n

Get the provider's relay hostname, port, authentication method, TLS requirements, and permitted sender address before changing settings.<\/p>\n

  1. Decide whether the relay is global or specific to this site. Inspect existing overrides first.<\/li>
  2. Configure the provider's host, port, credentials, and TLS mode at that scope. Global keys include smtp_relay<\/code>, smtp_host<\/code>, smtp_port<\/code>, smtp_username<\/code>, smtp_password<\/code>, and smtp_ssl<\/code>; site relay settings use different smtp_relay_*<\/code> keys.<\/li>
  3. Apply the documented reload or restart and check the effective settings without exposing credentials.<\/li>
  4. Arrange the provider's required domain verification and DNS records with the domain owner.<\/li>
  5. Send one representative message to an address you control, such as a password-recovery message or form receipt.<\/li>
  6. Check Zotonic's mail status, the provider's delivery status, and the recipient inbox. Confirm the sender and reply address are correct.<\/li><\/ol>\n

    Server acceptance and inbox delivery are different outcomes. Follow the mail-diagnosis task if delivery fails. Never disable certificate checks to work around a TLS mismatch; verify the provider's hostname and connection mode.<\/p>"}},"category_id":{"id":2773,"is_a":["meta","category"],"name":"adminguide","title":"Administration guide","uri":"https:\/\/zotonic.com\/id\/adminguide"},"content_group_id":{"id":339,"is_a":["meta","content_group"],"name":"default_content_group","title":{"_type":"trans","tr":{"en":"Default Content Group"}},"uri":"https:\/\/zotonic.com\/id\/default_content_group"},"created":"2026-10-07T11:12:59Z","creator_id":{"id":1,"is_a":["person"],"name":"administrator","title":"Site Administrator","uri":"https:\/\/zotonic.com\/id\/1"},"doc_editorial_bundle":true,"doc_editorial_edges":{"relation":[3065,3068,3081],"subject":[2554,2566,2595,2603]},"is_authoritative":true,"is_dependent":false,"is_featured":false,"is_protected":false,"is_published":true,"is_unfindable":false,"language":["en"],"modified":"2026-10-07T11:13:17Z","modifier_id":{"id":1,"is_a":["person"],"name":"administrator","title":"Site Administrator","uri":"https:\/\/zotonic.com\/id\/1"},"name":"admin_outbound_email","pivot_geocode":null,"pivot_location_lat":null,"pivot_location_lng":null,"privacy":0,"publication_end":"9999-06-01T00:00:00Z","publication_start":"2026-10-07T11:12:59Z","slug":"configure-outbound-email-and-verify-delivery","summary":{"_type":"trans","tr":{"en":"Set a relay at the correct scope and test a real site message."}},"title":{"_type":"trans","tr":{"en":"Configure outbound email and verify delivery"}},"title_slug":{"_type":"trans","tr":{"en":"configure-outbound-email-and-verify-delivery"}},"tz":"UTC","uri":null,"version":18,"visible_for":0},"uri":"https:\/\/zotonic.com\/id\/3067","uri_template":"https:\/\/zotonic.com\/id\/:id","websub":{"hub":"https:\/\/zotonic.com\/.zotonic\/websub","topic":"https:\/\/zotonic.com\/.zotonic\/websub\/topic\/3067"}},"status":"ok"}
