Sending E-mail from Powershell Failing on One Machine

I have a bit of powershell to send an e-mail:

$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($emailFrom, $emailTo, $subject, $body)

This works perfectly on every machine I've ever tried it on until today. I have one machine where I get this error message:

Exception calling "Send" with "4" argument(s): "Failure sending mail." At R:\sqlrestore\scripts\Utilities\Check-Lag.ps1:15 char:12 + $smtp.Send <<<< ($emailFrom, $emailTo, $subject, $body) + CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : DotNetMethodException

We'll need to know what values you are passing in as parameters please: $smtpServer, $emailFrom, $emailTo, $subject, and $body. – Richard

The error message is ambiguous. It turns out the issue is that the SMTP server was inaccessible because outbound SMTP traffic was not allowed.

By the way, if you're using PowerShell 2.0 then you may want to try the Send-MailMessage cmdlet:

Send-MailMessage -SmtpServer YourServerName -From $emailFrom -To $emailTo -Subject $subject -Body $body

I have just come across the same problem, turns out it was because of two factor authentication. I created a 'app specific password' in Google security settings and all works fine now.
