Background

Yesterday, I had a script that I could not get email notification to go out on.

Rather than installing Blat or other email command line tools, I opted to use PowerShell.

Code

Powershell

Script

Set-StrictMode -Version Latest

$script:ErrorActionPreference = "Stop"

[string] $FORMAT_TIMESTAMP = "dddd yyyy-MMM-dd HH:mm tt";

[string] $FORMAT_FQDN = "{0}@{1}";

[string] $emailAddressFrom = "";

[string] $serverSMTP = "<smtpserver>";

[string] $emailAddressReceipient ="<emailAddressReceipient>";

[string] $emailSubject ="Test Email";

[string] $emailBodyPrefix = "Test Email";

[string] $domainDefault = "self";

[string] $computerFQDN = "";

$tsAsString = Get-Date -Format $FORMAT_TIMESTAMP;

$objWMIComputerSystem = Get-WmiObject -Namespace root\cimv2 -Class Win32_ComputerSystem | Select Name, Domain

$computer = $objWMIComputerSystem.Name;

if ($objWMIComputerSystem.Domain -ne $null ){ `

	$domain = $objWMIComputerSystem.Domain;

}

if ( ($domain -eq "" ) -or ($domain -eq $null )) { `

	$domain = $domainDefault;
}

$computerFQDN = $FORMAT_FQDN -f $computer, $domain

$emailAddressFrom = $computerFQDN;

$emailBody = $emailBodyPrefix + " sent on " + $tsAsString

$emailBody;

Send-MailMessage `
	-SmtpServer $serverSMTP `
	-From $emailAddressFrom `
	-To $emailAddressReceipient `
	-Subject $emailSubject `
	-Body $emailBody
