Select file and email to yourself with one click

My current attachment emailscript uses the MailMessage method, but this method is obsolete (see: https://github.com/dotnet/platform-compat/blob/master/docs/DE0005.md). So I followed the recommendation, and used the MailKit Powershell Module to send emails.

Updates:

  1. Use of MailKit to send emails (requires installation of the MailKit Powershell Module).
  2. Added an "Install" procedure. Automate user settings.
  3. Added a "setPassword" procedure. Secure password entry and password storage in USERPROFILE (no plain text password anywhere).

Works with:

  • Windows Explorer Context menu (right click file and send email)
  • Command line (file parameter must have absolute/complete file path)
  • Drag and drop (create a Deaktop shortcut to the psEmailAttachment.ps1 script and drag a file to the shortcut be emailed)

 Installation procedure:

  1. Install the MailKit Module (e.g.: PS C:\> Install-Module -force -Name "Send-MailKitMessage" -Scope CurrentUser)
  2. Store the psEmailAttachment.ps1 script in some folder
  3. Update the email server properties and your email address in the psEmailAttachment.ps1 script
  4. Run:
    • Powershell -file psEmailAttachment.ps1 -install     #--- Create the Explorer context menu entry
    • Powershell -file psEmailAttachment.ps1 -setPassword #--- Setting the password of the email sender account.
Done.

Sending an email from Windows Explorer-> Right click filename:

psEmailAttachment.ps1

using module Send-MailKitMessage
<#

    To install the MailKit:
    PS C:\> Install-Module -force -Name "Send-MailKitMessage" -Scope CurrentUser #--- Install Module only for this user. User privileges only.
   
    Or:
    PS C:\> Install-Module -force -Name "Send-MailKitMessage" -Scope AllUsers           #--- Install Module for all users. Administrative privileges needed.
