I have written this article to understand how email can be sent using System.Net.Mail.MailMessage .net object with PowerShell. Below is the complete documentation regarding this object https://learn.microsoft.com/en-us/dotnet/api/system.net.mail.mailmessage?view=net-7.0. Although you can use simple and plain Send-MailMessage PowerShell cmdlet. It's always good to know multiple ways to do the same tasks.
Below is the function I have created to send email messages.
Function Send-Email { [CmdletBinding()] param ( [String]$From, [String[]]$To, [String]$Subject, [String]$SMTPServer, [String]$Body, [String[]]$Attachments ) $email = New-Object System.Net.Mail.MailMessage $From, $To, $Subject, $Body #$email.To.Add($To) $email.isBodyhtml = $true $smtp = new-object Net.Mail.SmtpClient($SMTPServer) #$smtp.Port = 587 $emailAttachment = new-object Net.Mail.Attachment($Attachments) $email.Attachments.Add($emailAttachment) $smtp.Send($email) }
After executing this function, below are the Parameter and uses for new cmdlet function. Its very easy to use.
Send-Email ` -From '[email protected]' ` -To '[email protected]' ` -Subject 'Test Email' ` -SMTPServer 'emailexchange.vcloud-lab.com' ` -Body 'This is test email' ` -Attachments 'c:\Temp\testfile.txt'
In case if you are not using any attachment, you can add below to skip attachment using if condition in the function.
if ($attachments -ne $null) {
$emailattachment = New-Object System.Net.Mail.Attachment($attachments)
$email.Attachments.Add($emailattachment)
}
This is another way of sending email using System.Net.Mail API. This uses only .net Object System.Net.Mail.SmtpClient. It is a breakdown of the above script only, but it is a little smaller code compare to above API.
Download this Send-Email script here or it is also available on github.com/janviudapi.
$from = '[email protected]' $to = '[email protected]' $subject = 'Test email message' $body = 'This is test email message' $smtpServer = 'emailexchange.vcloud-lab.com' $SMTPClient = New-Object System.Net.Mail.SmtpClient($smtpServer, 587) $SMTPClient.EnableSsl = $false $SMTPClient.Credentials = New-Object System.Net.NetworkCredential('[email protected]', 'Computer@1') $SMTPClient.Send($from, $to, $subject, $body)
