powershell email smtp with startls

Question

Need to send email via private smtp server with credential and starttls. I read many tutorials and still cannot establish starttls communication.

My code:

 $smtpServer = "smtp.xserver.cz" #Creating a Mail object $msg = new-object Net.Mail.MailMessage #Creating SMTP server object $smtp = new-object Net.Mail.SmtpClient($smtpServer, 25)#587 works $smtp.EnableSsl = $false $smtp.Credentials = New-Object System.Net.NetworkCredential("[email protected]","mypassword"); #yes, correct login, tried via Thunderbird #Email structure $msg.From = "[email protected]" $msg.To.Add("[email protected]") $msg.subject = "subject" $msg.IsBodyHTML = $true $msg.body = "AAA"+"<br /><br />" $ok=$true try{ $smtp.Send($msg) Write-Host "SENT" } catch { Write-Host "`tNOT WORK !!!!!" $error[0] $_.Exception.Response $ok=$false } finally{ $msg.Dispose() } if($ok){ Write-Host "`tEVERYTHING OK" }

Need to use .Net objects and class, not third party library, or Send-MailMessage in Powershell, because Send-MailMessage doesn't have atachment sending options.

You're not getting your TLS connect because you've set EnableSsl to $false.

Not sure where you got the idea that Send-MailMessage doesn't have attachment sending options. Sending attachments with Send-MailMailMessage is ridiculously easy. It accepts one or more file names to use as attachments from the pipeline, or through the -Attachments parameter.

I also tried enableSSL to true, but not sure, which port used... Please help me with code. Sorry, my mistake - Send-MailMessage is not acceptable due to send Credentials to my private smtp server.

Usually TLS is implemented on the same port (25), or on 587. Send-MailMessage also has a -Credential parameter.

I tried 25 and 587, nothing works. Yes, -Credentials parameters is there, but it is credential for running script on Windows, not for server's remote connection.

See this thread: stackoverflow.com/questions/12460950/… As for the TLS, the port for that will be configured on the mail server, so I can't tell you what it is (and whether it even supports TLS).

I tried my login via Thunderbird. With configuration noTLS on smtp, there was error with outgoing emails. But when I set StartTLS, everything works. So, there I can see port 25, StartTLS configuration, but still cannot establish connection throught Powershell. I also tried PhpMailer library. How is it possible, that Thudenrbird can send email and my script no?
