Outgoing Port 25 Connectivity Test

A Terraform script is provided to create a new VM that will verify outgoing port 25 is not blocked in the subscription for implementing the Client-hosted Email Signature Server solution.

• Create a Linux based VM to confirm outgoing port 25 availability on new Virtual Machines.
• The resources the Terraform script creates will be contained within a single Resource group.
• After the results of the port 25 check have been verified this Resource group can be deleted.

• In Cloud Shell change into the clouddrive folder:
  cd clouddrive

• Create a new directory for the terraform files:
  mkdir port25check; cd port25check

• Download and extract the port25check terraform scripts:

  curl -O https://download.templafy.com/delivery/ESS/port25check.zip

  unzip port25check.zip
• Run ./tf-run.bat in your open Cloud Shell to run the Terraform scripts that will create the port 25 check VM.

• The output will return the URL to check the results of the port 25 connectivity test.
   

Delete the test resources

• From the port25check directory in Azure Cloud Shell:
  terraform destroy -auto-approve

• From the Azure Portal:
