Trouble sending email using Powershell

Question

I've run the following script:

PS C:\> Send-MailMessage -To <EmailAddress1> -From <EmailAddress2> -Body "This is a test" -Subject "TEST MAIL" -SmtpServer <INTERNAL IP OF SMTP SERVER>

And I receive the following error:

Send-MailMessage : Unable to read data from the transport connection: net_io_connectionclosed.

At line:1 char:17
+ Send-MailMessage <<<<  -To <EmailAddress1> -From <EmailAddress2> -Body "This is a test" -Subject "TEST MAIL" -SmtpServer <INTERNAL IP OF SMTP SERVER>
+ CategoryInfo: InvalidOperation: (System.Net.Mail.SmtpClient:SmtpClient) [Send-Mail Message], SmtpException
+ FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage`

I was made aware of the fact that I need permissions to send email from my local machine through the SMTP server, and as far as I know, I've been granted those rights.

Would somebody please help point me in the right direction on this one?

The ultimate goal is to be able to send emails as part of some Powershell scripts.

Thanks!

Thanks for the help guys. I searched the web for that error message, and came up dry (there were results but they were unclear).Just thought I'd ask here. Thanks again. — PleaseHelpTheNewGuy

I prefer the Net.Mail.SmtpClient method of sending email. This script would send the contents of a file passed as a parameter.

$emailFrom = "[email protected]"
$emailTo = "[email protected]"
$subject = "TEST"
get-content $Args[0] | %{$Body+= " {0} `n" -f $_}
$smtpServer = "mailserver.somehost.com"
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($emailFrom, $emailTo, $subject, $body)

Though, your error sounds more like a networking issue of some type.

You might want to check that you can reach the SMTP port on the server:

Thanks for the help. I will have to wait for the admin to be available. I tried to telnet to the server; couldn't connect. I'm guessing there's some permission that isn't correctly set. Once I get this working, I will look into using your method, although your 4th line of code is a little unclear to me. I'm accepting your answer. Thanks again!

In the 4th line of code, I am dumping the file contents into the body of the email. $Args[0] contains the file name I passed into the script.

As the error message from Send-MailMessage shows, it too "just" uses System.Net.Mail.SmtpClient to do its work.

Probably your antivirus file service is locking mail delivery.
