Using SMTP in PowerShell

Dominik Deák

1 Introduction

This repository contains sample code demonstrating how to take advantage of .NET libraries in PowerShell to facilitate email communications without using an actual email client.

Warning: This is a demo only. These scripts are not intended to be used directly in a production environment.

2 Instructions

2.1 Prerequisites

Before using the demo code, the following tools and libraries are required. You may skip this section if these prerequisites are already installed.

• PowerShell 6: https://github.com/PowerShell/PowerShell/releases

2.2 Configuration

1. Create a new email address dedicated for experimentation purposes. This way you don't need to worry about accidentally deleting important messages.

2. Edit the PowerShell script file Source\SendMail.ps1 and supply the outgoing SMTP server configuration, including the credentials needed for authentication:

   # Outgoing email configuration used for sending messages
   $outgoingUsername           = ""
   $outgoingPassword           = ""
   $outgoingServer             = ""
   $outgoingPortSMTP           = 587   # Normally 25 (not secure), 465 (SSL), or 587 (TLS)
   $outgoingEnableSSL          = $true
   $outgoingFromAddress        = $outgoingUsername
   $outgoingReplyToAddressList = @()
   $outgoingToAddressList      = @()
   $outgoingCCAddressList      = @()
   $outgoingBCCAddressList     = @()
