      Article summary

      Applies to: Lasernet 11

      Used for sending a job as email via the SMTP protocol.

      The Setup tab for a Mail Output module.

      Connection

      X-Mailer

      By default, the X-Mailer header identifies that Lasernet has created the email message. The field is optional and if left blank the X-Mailer will not appear in the email message.

      Server Address

      Host name or IP address of SMTP server.

      Port

      Port number of the SMTP server.

      Security

      Selectable choices for security protocols are Auto, SSL 3.0 or TLS. Activate SSL port and set up the port number (default 465) to provide encrypted communication and secure identification. Configure the TLS protocol to use specifically version 1.0, 1.1, 1.2 or 1.3 of the protocol or configure it to negotiate with the server the use of a particular version or higher (for example, 1.2 or higher).

      Timeout

      If the connection cannot be established by the timeout has been reached, the attempt will be abandoned. Default Timeout is 30 seconds.

      EHLO string

      Set up the IP address for identifying the client (Lasernet) against the SMTP server.

      Authentication

      Select None, Basic authentication, or OAuth2 (Microsoft application registration) authentication.

      Username (Basic authentication only)

      A username with access to send the e-mail via the SMTP server.

      Password (Basic authentication only)

      The password for the above username.

      Tenant Domain (OAuth2 authentication only)

      Tenant domain of the app registration.

      Client ID (OAuth2 authentication only)

      Client ID of the app registration.

      Client secret (OAuth2 authentication only)

      Client secret of the app registration.

      OAuth2 Configuration

      To set up OAuth2 authentication, you must complete tasks in Microsoft Entra ID and Exchange in addition to configuring this Lasernet module.

      Follow this overall process:

      1. In Entra ID, create an application registration for Lasernet and then grant it the following permissions:

        • For POP access: POP.AccessAsApp

        • For IMAP access: IMAP.AccessAsApp

        • For SMTP access: SMTP.SendAsApp

      2. In Entra ID, get tenant admin consent for the Lasernet application registration to access Exchange mailboxes through POP, IMAP, or SMTP.

      3. In Exchange, use the New-ServicePrincipal cmdlet to register the service principal.

        • Note: This step must be completed by an Exchange administrator.

      4. In Exchange, use the Add-MailboxPermission cmdlet to grant the application the necessary access to specific mailboxes.

        • For example: Add-MailboxPermission -Identity "john.smith@example.com" -User 3f2504e0-4f89-11d3-9a0c-0305e82c3301 -AccessRights FullAccess

      Note

      Properties

      A screenshot of a computer AI-generated content may be incorrect.  

      Name

      From e-mail name.

      Address

      From e-mail address.

      Return Path

      The mail address to bounce back the mail to in case of failure.

      S/MIME: Sign

      Signs the email with the S/MIME certificate associated with the Address in the From E-mail area. (This requires that the certificate is imported into Microsoft Windows on the machine running the Lasernet service.)

      S/MIME: Encrypt

      Encrypts the email with each S/MIME certificate associated with each recipient’s addresses. (This requires that the certificate for each receiver is imported into Microsoft Windows on the machine running the Lasernet service.) If not, all receiver certificates are available, no e-mail is sent.

      Request Delivery Receipt

      If selected, a delivery receipt will be sent to the e-mail address when the message is successfully delivered to the recipient.

      Request Read Receipt

      If selected, a receipt will be sent to the e-mail address when the recipient has opened the e-mail.

      Do not insert job data in an attachment

      If selected, job data will not be inserted as an attachment in the e-mail. Used if you only want a mail body to be presented (other attachments can still be added via the MailAttachment functionality; see information in JobInfos about MailAttachment and MailAttachmentFileName).

      Importance

      Set the category of importance to Low, Normal (default) or High.

      Headers

      Optionally, you can add custom MIME headers to the emails sent by a Mail Output module. Some possible uses for custom headers are to enable the sending organization to troubleshoot delivery issues by examining unique codes in the header data in bounced emails, and to enable enhanced workflow visibility by enabling the organization to track emails back to their originating Lasernet process or job.

      The Mail Output module will add the configured custom headers to outgoing email and give each header the specified value.

      You can specify a static value for a header; for example, Lasernet Mail. Else you can use JobInfo substitution if you want header values to be dynamic. For example, you could enter a JobInfo reference (like #InvoiceNumber#) as the header’s Value.

      If a mail is bounced back to the sender and is read by Lasernet’s Mail Input module, Lasernet creates JobInfos that have names and values corresponding to the custom headers in the bounced email.

      The Headers tab of the Mail Output module.

      Name

      The name of the custom header added to email.

      Value

      Set a value for the header. Supports JobInfo substitution.
