Add an SMTP B2B connection

Select the Main Menu icon .
Select Extensible Tracelink Transfer.
Select B2B Connections in the side menu.
Select the SMTP (Email).
Select the New button to add a new SMTP B2B connection.
The New SMTP Connection screen is displayed.
Fill in the following fields in the General section:
- Connection Name field - Enter a unique name for the SMTP B2B connection. This name is a global identifier and serves as the email prefix (the part before the “@” sign) where messages are sent. This field cannot be edited after the connection is successfully saved. Use the following naming conventions:
  - Must be between 4 and 100 characters.
  - Must start with an uppercase letter or number.
  - Can contain uppercase letters, numbers, hyphens (-), and underscores (_).
  - The “@” character is not allowed (to avoid confusion with email addresses).
- DKIM Authentication switch – When the DomainKeys Identified Mail (DKIM) Authentication is set to Yes, all inbound emails to the SMTP (Email) B2B connection must successfully pass DKIM verification to be accepted and processed. Emails that pass authentication proceed to the next stage of processing. Emails that fail DKIM authentication are rejected and not processed and records a warning in the logs.
- DMARC Authentication switch – Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that builds on SPF (Sender Policy Framework) and DKIM. It enables domain owners to define how email servers should manage messages that do not pass SPF or DKIM verification.
- SPF Authentication switch – Sender Policy Framework (SPF) authentication is an email authentication protocol that helps prevent email spoofing by allowing domain owners to specify which mail servers are authorized to send emails on behalf of their domain.
- Inbound Allowlist Domains – A list of domains from which the SMTP (Email) B2B connection will accept emails. Fill in the following fields in the Inbound Allowlist Domains group by selecting the Add icon:
  - Allowed Domain – The name of the domain that will be allowed for an inbound B2B message.
The following fields in the Details section are auto-populated:
- Created By User field – The name of the entity that created the B2B connection. This field is auto-populated when the connection is successfully saved and cannot be edited.
- Last Updated By User field – The name of the entity that recently updated the connection. This field is auto-populated when the connection is successfully saved and cannot be edited.
- Last Updated Date/Time field – The date and time when the B2B connection was last modified. This field is auto-populated when the connection is successfully saved and cannot be edited.
- Creation Date/Time field – The date and time when the B2B connection was initially created. This field is auto-populated when the connection is successfully saved and cannot be edited.
Select the Add icon in the Inbound Configuration section. To send an inbound B2B message, configure the required message settings in the Add Inbound Email side panel, to send a message to the TraceLink‑generated email address associated with the connection:
- Base Email Address – Required. A descriptive name that is used to generate a unique email address for the specified B2B message. For example, purchase-orders.
- B2B Message drop-down – Required. Select the type of business document or message to associate with the generated email address. When a Partner sends an email to that address, the selected message type determines the canonical schema and transformation logic applied to the inbound message.
- Receiving Partner drop-down – Optional. Specifies which partner (company) within the TraceLink network should receive and process the inbound message.
  While selecting the Receiving Partner:
  - Separate Email Addresses for Each Partner - Configure a unique inbound email address for each partner. Each partner uses its assigned address to send B2B messages to the system.
  - Single Email Address for All Partners - Set up one inbound email address for all partners to send B2B messages (e.g., compliance exceptions, purchase orders). This option simplifies configuration and reduces the number of email addresses to manage.
- Generated Email Address (Inbound) – A unique email address is automatically generated when the SMTP (Email) B2B connection is successfully saved. It determines which transaction type and (optionally) which Owner or Partner the inbound message is for. This ensures the message is routed to the correct business process and transformed using the right logic.
1. Select the Add icon in the Allow Senders section to add a new sender:
  - Allowed Sender – Enter the individual email addresses permitted to send inbound messages for this B2B Message and its Receiving Partner. To allow all senders from a specific domain, use the Inbound Allowlist Domain option.
Select Apply to save the changes.
Select the Add icon in the Outbound Configuration section. The outbound configuration defines how outbound B2B messages are delivered through email. It specifies the Partner recipients, associates each recipient list with a Message type, identifies the reply‑to address, and automates the exchange of business documents between members on the TraceLink network.
Fill the following details in the Add Outbound Configuration side panel:
- B2B Message drop-down – Required. Select the business document or message type supported by TraceLink. This selection ensures that only outbound configurations for the specified message type are used when sending messages.
- Sending Partner drop-down – Optional. To send B2B messages to different recipients based on the Partner sending the message, select the specific Partner. Leave this field blank to send messages to the same recipients for all Partners.
- Include Sender Configured Recipients switch – Optional. A Boolean option that enables additional recipients configured by the sender. When enabled, any recipients specified by the sender at the time of sending are included in the distribution list.
- Select the Add icon in the Recipients section to send email to the listed recipients.
  - Recipient field – Enter the email address of each recipient for the B2B message. All specified recipients receive a copy of the outbound B2B message.
- Select the Add icon in the Actionable Emails section to set email address that will be set as the Reply-To in the outbound email.
- Reply-To Email Addresses field - Enables routing of recipient replies to a specific inbound email address. Use this field to support automated or manual response workflows. To allow recipients to respond to B2B messages, enter one or more reply‑to addresses. For example, use a purchase order acknowledgment address for replies to purchase orders, or an exception address for replies that include comments. Use the generated inbound email address as the reply‑to if responses must be processed automatically.
