Send email from a PaaS application

This page describes how to send emails using Sikts email infrastructure from applications running in Kubernetes.

Email from PaaS Kubernetes​

Pods running in the PaaS can send email using:

outbound-mta.it.sikt.no:587

The PaaS workers are whitelisted so there is no authentication or client certificate required.

info

Sender address in emails must end with one of the following domains, in both From: header and Return-Path: header:

  • @feide.no
  • @sigma2.no
  • @sikt.no

If they don't, they will be transformed into a @srs.it.sikt.no address, which will work, but is not pretty, so they may confuse some recipients, break things like inbox mail filters, etc.

If you want to use a custom sender address and have an AWS account, you can look into sending email from apps running on AWS.
