Emailing in the Cloud
Planon Live can send email notifications using either the shared Planon SMTP service (default) or a customer-managed SMTP service. Email communications are performed using the standard SMTP protocol. Additional security has been configured using SPF and DKIM. Encrypted email is not supported through the standard SMTP integration.
Using a customer-managed SMTP service (recommended)
When customers want to send emails using their own domain name, Planon strongly recommends configuring a customer-managed SMTP service.
Using a customer-managed SMTP service provides:
• Full control over the sending domain.
• Control of SPF, DKIM, and DMARC policies.
• Improved protection against domain spoofing.
• Better alignment with the customer's email security and compliance policies.
• Clear ownership and accountability for outgoing email communications.
Recommendation: Customers who wish to use their own domain name for sending mail should always opt for their own SMTP service instead of relying on the shared Planon SMTP service.
Using the Planon shared SMTP service
The Planon shared SMTP service can be used for standard email notifications from Planon Live. However, customers are not recommended to use the shared SMTP service in combination with the custom domain feature.
The Planon SMTP service is a shared service that is used by multiple customers. When a custom domain is configured while using the shared SMTP service, other parties that are trusted by the shared mail infrastructure may be able to send emails using that same custom domain. This can lead to sender authenticity, brand protection, and email trust concerns.
For this reason, the Planon shared SMTP service should only be used for generic Planon sender domains and not for customer-owned domains.
ESMTP with TLS support
Extended Simple Mail Transfer Protocol or ESMTP is a protocol used for sending and receiving email over IP networks. ESMTP includes additional functionality that SMTP does not support, such as Transport Layer Security (TLS). Planon provides ESMTP with TLS support over port 587.
 | Emails sent over the public internet are already encrypted with TLS. The ESMTP setup mentioned here refers to the communication between your Planon application and the Planon SMTP server. |
To set this up, enter the following values in these fields:
• ESMTP with TLS: Yes
• SMTP with SSL: No
