The SMTP ingress microservice listens on port :25 for incoming email messages. An app can listen to the appropriate event in order to process and act upon the email message.
Use the following prompt to listen to the event:
Add an inbound event sink to the OnIncomingEmail event of the SMTP ingress service.
TLS Termination
The SMTP ingress offers STARTTLS when a {port}-cert.pem / {port}-key.pem pair for its listening port is present in the working directory. A single cert/key per listening port is the only supported configuration here — SAN-indexed matching and live reload, available for the HTTP ingress proxy, do not apply. Rotating the cert requires restarting the SMTP ingress microservice.
