Connector
SMTP (Email)
Send rows to people: the relay the Send Email node delivers through. Separate from the instance alert relay in Settings, so business mail can go out on its own server and its own From domain.
Settings
What the connection form asks for. Every connection has a Staging side, which it needs, and an optional Production side with values of its own; both ask for the same settings.
| SMTP host | Your relay's hostname, e.g. smtp.office365.com, smtp.sendgrid.net, or an internal Exchange server. A private certificate works: Trinium trusts the operating system's certificate store, so an internal CA installed in the image is honoured. |
| Port | Leave blank to use the default for the security setting: 587 for STARTTLS, 465 for TLS, 25 for none. |
| Security | Chosen explicitly rather than guessed from the port, so a mismatch fails as a clear refusal instead of an unreadable handshake error. Choices: STARTTLS (usually port 587); TLS / SSL (usually port 465); None: plain SMTP (port 25). |
| Sign in | Many internal relays accept mail from a known IP with no credentials at all. Choices: Username and password; No sign-in (an internal relay that trusts this server). |
| Username | Shown when Sign in is Username and password. |
| Password | Shown when Sign in is Username and password. Stored encrypted, and never shown again after you save it. |
| From address | The address every message is sent as. Relays routinely refuse a sender they do not own, so this must be one this relay is allowed to send as; it is not derived from anything. |
| From name | The display name shown beside the address, e.g. Acme Reporting. Optional. |
| Allowed recipient domains | Leave blank to allow any recipient. Otherwise list the only domains this connection may send to, separated by commas, e.g. acme.com, partner.com. Every To, Cc and Bcc address is checked before a single message goes out, and a run that would mail anyone else is refused. Subdomains are not included, so list eu.acme.com separately. |
Testing the connection
Test connects, starts encryption as configured, signs in and disconnects. It sends no mail, and a wrong password fails. Send test email sends one real message, and is recorded in the audit trail.
Good to know
- This relay is the one the Send Email node delivers through. It is separate from the relay Trinium uses for its own alerts (Settings), so business mail can use another server and another From address.
- Allowed domains bounds where the relay may deliver: one recipient outside the list stops the whole run.
- A relay with a certificate from your own internal certificate authority works, because Trinium trusts the operating system's certificate store.
