Swaks Email Scripting

Hi, in this blog post I will show you how I configured Swaks for sending emails using SMTP using my custom SMTP server.

First I ran the following command to install swaks:

sudo apt-get install swaks

With swaks installed, I could start building a test command just to
see if this would actually work. I started with the below command:

swaks --to destination@email.com --from source@email.com --auth --auth-user=source@email.com --auth-password=passwordforsource@email.comaccount --server smtp.example.com -tls

This gave me an error along the lines of “Could not authenticate – connection refused” after talking to the people hosting my SMTP server, I found out that I needed to make sure that I was using port 587 and not the default port of 465.

So I made sure that my command explicitly used that port by adding it to the server parameter and managed to get an email to successfully send. You can see the code I used below:

swaks --to destination@email.com --from source@email.com --auth --auth-user=source@email.com --auth-password=passwordforsource@email.comaccount --server smtp.example.com:587 -tls

Extra

I wanted to use this in a script so that I could launch the script and an email would get sent. I also wanted to change what would get sent in the actual email since currently, it was just using the default values.

After 5 or so minutes of cobbling a script together, I came up with what you can see below:

#!/bin/bash

hostname=$(hostname)
uptime=$(uptime)

swaks --to destination@email.com \
--from=source@email.com \
--auth \
--auth-user=source@email.com \
--auth-password=password-for-source-email \
--server smtp.example.com:587 \
--body "$hostname - uptime is $uptime" \
--header "Subject: $hostname is still up" \
-tls \

Now I can send this email whenever I want, I even created a CRON job to send the email every hour. Enjoy!

LAPS Winform

*UPDATE*

I have created the *final* iteration of this WPF form which can be found here

*UPDATE*

I didn’t like having to remote desktop into my domain controller and couldn’t figure out if there was a LAPS tool included in RSAT tools so I decided just to make my own and to add some extra features.

I wanted the GUI to look pretty much identity to the actual LAPS GUI. You can see the difference below:

You might be able to see that I  changed the “Set” button to say “Set and Update”. This was because I wanted the form to also attempt to update the group policy settings on the computer so that it would get a new password a lot quicker than the original GUI.

There’s not much else I can say, I will leave the entire script below for you to copy and paste. You will need to add the domain controller for your environment in the $domaincontroller variable at the top of the script. I have converted this to an EXE and run whenever I need it, never skips a beat. Let me know how you get on with it. Enjoy!

Mailto in SharePoint String Builder

Bit of a weird, one off sort of thing. I was creating a workflow in SharePoint which would send an email. On this email would be an “Approve” and “Decline” button. The decline button was easy enough to do but the approve button turned out to be a complete pain in the back side.

First of all, I would like to tell you to not use mailto whenever you can. There are better programs out there. Trust me. If anyone knows any really good ones that they standby please feel free to leave a comment.

The mailto syntax is basically this:

mailto:RECIPIENT?cc=CCRECIPIENT&subject=SUBJECT TEXT&body=BODY TEXT

This looks simple enough but once you want to start doing some more complicated features/formatting that would otherwise be quite simple in HTML, become near impossible here. Especially with it being in a SharePoint string builder box.

What I wanted was for there to be three lines of text, two in which got information from the SharePoint form to fill in the information and one for adding text. By the way if you didn’t know, to add a new line you can use “%0d0d“.

That’s: percent sign – zero – delta – zero – delta

This is the final code that I ended up with:

mailto:RECIPIENT@EMAIL.COM?cc=[%Current Item:Created By%]&subject=Approval Authorisation for [%Current Item:Created By%]&body=The remote access request for [%Current Item:Created By%] has been approved by [%Current item:Manager's Name%]%0d%0dThe reason for approval is - [%Current Item:Reason for approval%]%0d%0dPlease specify any limitations below:

Here is a picture just in case you want to see it and below that what the actual email looks like:

String Builder

Email

I would like to add that you will have to change the “Add or Change Lookup” so that it finds the “Display Name”, otherwise the users will show as the default SharePoint format which isn’t as good looking. You can see this below:

Display Name

Hope you enjoyed and found this useful. I may to an entire blog trying to outline the possibilities of using the SharePoint string builder and “Define E-Mail Message” features. Suppose you’ll have to wait and see.

More Auto-Loading, Custom PowerShell Scripts

In this update, you’ll see how I added two or three new scripts to the environment and also changed how most of the scripts work.

One new script that I add was a script that would take CSV data and add the users to a group in Active Directory. You can see this below:

function Get-CSVAddToGroup{
 <#
 .SYNOPSIS
 This function allows you to add usernames from a CSV to a specified Active Directory group.
 It needs confirmation for each addition to a group.

 .EXAMPLE
 Get-CheckCSVAddToGroup -Groupname "all rossendale staff" -path c:\testing\test.csv

 #>
 [cmdletbinding()]
 param(
 [parameter(Mandatory=$true)]
 [string]$groupname,

 [parameter(mandatory=$true)]
 [string]$path
 )

 $csvformembership = Import-Csv -Path $path

 foreach ($b in $csvformembership){
  $name = $b.user
  Add-ADGroupMember -Identity "$groupname" -Members $name -Confirm
 }
}

Another script I added was my script for sending messages to remote computers on the network. You can see this below:

function Send-Message{

 function send-messagewithname{
  $name = Read-Host "Enter a name"
  $msg = Read-Host "enter a message"
  $adcompstocheck = Get-ADComputer -LDAPFilter "(name=$name)" -Properties name

  if ($adcompstocheck -eq $null){
   Write-Host "$name doesn't exist!"
   pause
  }else{
   Invoke-WmiMethod -Path win32_process -Name create -ArgumentList "msg * $msg" -ComputerName "$name"
  }
 }

 function send-messagewithip{
  $ip = Read-Host "enter an IP"
  $msg = Read-Host "enter a message"
  $adcompstocheckip = Get-ADComputer -Filter * -Properties ipv4address, name | select ipv4address
  if ($adcompstocheckip -eq $null){
   write-host "$ip doesn't exist"
   pause
  }else{
   Invoke-WmiMethod -Path win32_process -Name create -ArgumentList "msg * $msg" -ComputerName "$ip"
  }
 }

 do {$nameorip = Read-Host "Do you want to use IP or Name (I or N)?"} while (("i","n") -notcontains $nameorip)
 if ($nameorip -eq "n"){
  send-messagewithname
 }else {
  send-messagewithip
 }
}

Finally, my last script that was added to my custom PowerShell environment allowed me to list all the computers on the network with a specific operating system. For example “2012” or “Professional”. The code for this is below:

function list-OSVersonComputers{
 <#
 .SYNOPSIS
 This function allows you to list all of the computers with the requested OS version.

 .EXAMPLE
 List-OSVersionComputers -OSVersion 2012

 .EXAMPLE
 List-OSVersionComputers -OSVersion standard
 #>
 [cmdletbinding()]
  param(
  [parameter(mandatory=$true)]
  [string]$OSVersion
 )

 $OSVersion2 = '*' + ($OSVersion) + '*'

 Get-ADComputer -Filter {OperatingSystem -like $OSVersion2} -Property * | Format-Table name,operatingsystem,lastlogondate -Wrap -AutoSize
}

I also added help menus to most of my scripts to make them more professional.

Customized Email Signatures In HTML

Back off holiday, want to do something simple. So email signature it is.

I made mine in the Mimecast administrator center as a way to become more familiar with HTML so that I could create an actual signature for some users.

Before we look at the code – I will put an image below of what the signature would actually look like. Also, I own NONE of the images/sites shown here. (Sorry, just didn’t want legal people sniffing around).

Signature

Now that you have seen the signature, you can see that is it in no way a real world example of something that should be used. But I also couldn’t use the actual one for…reasons. I just wanted to show you every feature I used in the real one.

Below is the actual code I used:

<html>
 <head>
 </head>
  <body><mc type="body">
  <p style="font-family:calibri:">This is a <b>test</b> email signature</p>

  <img src="http://combiboilersleeds.com/images/test/test-5.jpeg" alt="TEST LEFT" style="float:left;width:50px;height:20px;" />
  <p style="font-family:courier;">This is the second line of the test email signature</p>
  <p style="font-family:verdana;font-size:80%;">This is the last line of the test email signature</p>

  <img src="http://combiboilersleeds.com/images/test/test-5.jpeg" alt="TEST IMAGE" style="width:200px;height:70px;" />

Adding Signatures In Mimecast

Bit different from, the now usual, Powershell guides. Thought I’d do something different. This guide will show you how to add a custom signature to a user, multiple users’ or even globally.

Lets start off. You’ll want to log into your Mimecast administrative console, go to Service-Gateway-Policies. In here you should see “Stationary”. We want to create a new definition, so click on the “Definition” button on the “Stationary” listing.

Here you can click the “New Item” button. For the Description, obviously, enter a brief description of the new definition. The “Unique Identification Text” is used to scan an email that the definition is applied to to determine if the signature has already been added, so you want to add something that is in the signature and something that is unique to this signature. For the short code, enter a unique name. Below is an example of mine:

1

Now we want to edit the HTML so that there actually is a signature to put onto the emails. Click on the “Edit HTML” button and enter your signature. This is the code I added to mine:

<html>
 <head>
 </head>
  <body>
    <mc type="body">

    <font size="2" color="gray">
    This is a test email signature for marketing
    </font>

    <img src="IMAGE LINK" alt="ALTERNATIVE IMAGE NAME" style="width:214px;height:24px:" />

 </body>
</html>

So in my signature I have the message “This is a test email signature for marketing” and also a company logo.

Now we have that, we need to add it to an actual policy, otherwise it simply won’t be used by anything. Navigate back after saving your definition to the “Policies” page and click on the “Stationary” row. You now want to click “New Policy” which should open up a new policy creation window.

For the “Policy Narrative” enter a name for the policy, for the “Select Stationary”, select “lookup”, find your newly created definition and click “Select”. Since I created mine as a test and my Mimecast access is on my business email address, I configured an individual send and to email address for the policy to apply to. On this page you can also select when the policy will be active or even a range of source IP addresses.

Below are the values that I entered. The emails are removed for obvious reasons:

2

Finally, below is an example of an email with the newly added signature:

3

You should now have a custom signature that applies to every user defined in the policy instead of individual users.
