Send mail via Gmail with PowerShell V2's Send-MailMessage

I'm trying to figure out how to use PowerShell V2's Send-MailMessage with Gmail.

Here's what I have so far.

$ss = New-Object Security.SecureString
foreach ($ch in "password".ToCharArray())
{
    $ss.AppendChar($ch)
}
$cred = New-Object Management.Automation.PSCredential "uid@example.com", $ss
Send-MailMessage  -SmtpServer smtp.gmail.com -UseSsl -Credential $cred -Body...

I get the following error

Send-MailMessage : The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn

    + FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage

Am I doing something wrong, or is Send-MailMessage not fully baked yet (I'm on CTP 3)?

Some additional restrictions:

  1. I want this to be non-interactive, so Get-Credential won't work.
  2. The user account isn't on the Gmail domain, but a Google Apps registered domain.
  3. For this question, I'm only interested in the Send-MailMessage cmdlet. Sending mail via the normal .NET API is well understood.

Here's my PowerShell Send-MailMessage sample for Gmail...

Tested and working solution:

$EmailFrom = "notifications@somedomain.com"
$EmailTo = "me@earth.com"
$Subject = "Notification from XYZ"
$Body = "this is a notification from XYZ Notifications.."
$SMTPServer = "smtp.gmail.com"
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("username", "password");
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)

Just change $EmailTo, and username/password in $SMTPClient.Credentials... Do not include @gmail.com in your username...

I'm not sure you can change port numbers with Send-MailMessage since Gmail works on port 587. Anyway, here's how to send email through Gmail with .NET SmtpClient:

$smtpClient = New-Object system.net.mail.smtpClient
$smtpClient.Host = 'smtp.gmail.com'
$smtpClient.Port = 587
$smtpClient.EnableSsl = $true
$smtpClient.Credentials = [Net.NetworkCredential](Get-Credential GmailUserID)
$smtpClient.Send('GmailUserID@gmail.com', 'yourself@somewhere.com', 'test subject', 'test message')

I am really new to PowerShell, and I was searching about gmailing from PowerShell. I took what you folks did in previous answers, and modified it a bit and have come up with a script which will check for attachments before adding them, and also to take an array of recipients.

               ValueFromPipelineByPropertyName = $true)]
    [Alias('Attachment')]
    [String[]]$Arry_EmailAttachments
)

$SMTPServer = "smtp.gmail.com"
$SMTPClient = New-Object Net.Mail.SMTPClient($SmtpServer, 587)
$SMTPClient.EnableSSL = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("GMAIL_USERNAME", "GMAIL_PASSWORD");

# From Core @ stackoverflow.com
$emailMessage = New-Object System.Net.Mail.MailMessage
$emailMessage.From = $EmailFrom
foreach ($recipient in $Arry_EmailTo)
{
    $emailMessage.To.Add($recipient)
}
$emailMessage.Subject = $EmailSubj
$emailMessage.Body = $EmailBody
# Do we have any attachments?
# If yes, then add them, if not, do nothing
if ($Arry_EmailAttachments.Count -ne $NULL)
{
    $emailMessage.Attachments.Add()
}
$SMTPClient.Send($emailMessage)

Of course, change the GMAIL_USERNAME and GMAIL_PASSWORD values to your particular user and password.

I had massive problems with getting any of those scripts to work with sending mail in powershell. Turned out you need to create an app-password for your gmail-account to authenticate in the script. Now it works flawlessly!

I haven't used PowerShell V2's Send-MailMessage, but I have used System.Net.Mail.SMTPClient class in V1 to send messages to a Gmail account for demo purposes. This might be overkill, but I run an SMTP server on my Windows Vista laptop (see this link). If you're in an enterprise you will already have a mail relay server, and this step isn't necessary. Having an SMTP server I'm able to send email to my Gmail account with the following code:

$smtpmail = [System.Net.Mail.SMTPClient]("127.0.0.1")
$smtpmail.Send("myacct@gmail.com", "myacct@gmail.com", "Test Message", "Message via local SMTP")
