Powershell send-mailmessage - email to multiple re

问题:

I have this powershell script to sending emails with attachments, but when I add multiple recipients, only the first one gets the message. I've read the documentation and still can't figure it out. Thank you

$recipients = "Marcel <[e-mail]>, Marcelt <[e-mail]>"

Get-ChildItem "C:\Decrypted\" | Where {-NOT $_.PSIsContainer} | foreach {$_.fullname} |
send-mailmessage -from "[e-mail]" `
            -to "$recipients" `
            -subject "New files" `
            -body "$teloadmin" `
            -BodyAsHtml `
            -priority  High `
            -dno onSuccess, onFailure `
            -smtpServer  192.168.170.61

$recipients = "Marcel <[e-mail]>, Marcelt <[e-mail]>"

is type of string you need pass to send-mailmessage a string[] type (an array):

[string[]]$recipients = "Marcel <[e-mail]>", "Marcelt <[e-mail]>"

I think that not casting to string[] do the job for the coercing rules of powershell:

$recipients = "Marcel <[e-mail]>", "Marcelt <[e-mail]>"

is object[] type but can do the same job.

Just creating a Powershell array will do the trick

$recipients = @("Marcel <[e-mail]>", "Marcelt <[e-mail]>")

The same approach can be used for attachments

$attachments = @("$PSScriptRoot\image003.png", "$PSScriptRoot\image004.jpg")

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[e-mail]>', 'username2<[e-mail]>')
$emailFrom = 'SomeServer <[e-mail]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

You must first convert the string to a string array, like this:

$recipients = "Marcel <[e-mail]>,Marcelt <[e-mail]>"
[string[]]$To = $recipients.Split(',')

Then use Send-MailMessage like this:

Send-MailMessage -From "[e-mail]" -To $To -subject "New files" -body "$teloadmin" -BodyAsHtml -priority High -dno onSuccess, onFailure -smtpServer 192.168.170.61

That's right, each address needs to be quoted. If you have multiple addresses listed on the command line, the Send-MailMessage likes it if you specify both the human friendly and the email address parts.

to send a .NET / C# powershell eMail use such a structure:

for best behaviour create a class with a method like this

 using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                PowerShellInstance.AddCommand("Send-MailMessage")
                                  .AddParameter("SMTPServer", "smtp.xxx.com")
                                  .AddParameter("From", "[e-mail]")
                                  .AddParameter("Subject", "xxx Notification")
                                  .AddParameter("Body", body_msg)
                                  .AddParameter("BodyAsHtml")
                                  .AddParameter("To", recipients);

                // invoke execution on the pipeline (ignore output) --> nothing will be displayed
                PowerShellInstance.Invoke();
            }              

Whereby these instance is called in a function like:

        public void sendEMailPowerShell(string body_msg, string[] recipients)

Never forget to use a string array for the recepients, which can be look like this:

string[] reportRecipient = { 
                        "xxx <[e-mail]>",
                        "xxx <[e-mail]>"
                        };

body_msg

this message can be overgiven as parameter to the method itself, HTML coding enabled!!

recipients

never forget to use a string array in case of multiple recipients, otherwise only the last address in the string will be used!!!

calling the function can look like this:

        mail reportMail = new mail(); //instantiate from class
        reportMail.sendEMailPowerShell(reportMessage, reportRecipient); //msg + email addresses
