How to pass credentials to the Send-MailMessage command for sending emails

by

I found this blog site: Adam Kahtava
I also found this question: send-mail-via-gmail-with-powershell-v2s-send-mailmessage
The problem is, neither of them addressed both your needs (Attachment with a password), so I did some combination of the two and came up with this:

$EmailTo = "[email protected]"
$EmailFrom = "[email protected]"
$Subject = "Test" 
$Body = "Test Body" 
$SMTPServer = "smtp.gmail.com" 
$filenameAndPath = "C:\CDF.pdf"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
$attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
$SMTPMessage.Attachments.Add($attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
$SMTPClient.EnableSsl = $true 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential("username", "password"); 
$SMTPClient.Send($SMTPMessage)

Since I love to make functions for things, and I need all the practice I can get, I went ahead and wrote this:

Function Send-EMail {
    Param (
        [Parameter(`
            Mandatory=$true)]
        [String]$EmailTo,
        [Parameter(`
            Mandatory=$true)]
        [String]$Subject,
        [Parameter(`
            Mandatory=$true)]
        [String]$Body,
        [Parameter(`
            Mandatory=$true)]
        [String]$EmailFrom="[email protected]",  #This gives a default value to the $EmailFrom command
        [Parameter(`
            mandatory=$false)]
        [String]$attachment,
        [Parameter(`
            mandatory=$true)]
        [String]$Password
    )

        $SMTPServer = "smtp.gmail.com" 
        $SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
        if ($attachment -ne $null) {
            $SMTPattachment = New-Object System.Net.Mail.Attachment($attachment)
            $SMTPMessage.Attachments.Add($SMTPattachment)
        }
        $SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
        $SMTPClient.EnableSsl = $true 
        $SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom.Split("@")[0], $Password); 
        $SMTPClient.Send($SMTPMessage)
        Remove-Variable -Name SMTPClient
        Remove-Variable -Name Password

} #End Function Send-EMail

To call it, just use this command:

Send-EMail -EmailTo "[email protected]" -Body "Test Body" -Subject "Test Subject" -attachment "C:\cdf.pdf" -password "Passowrd"

I know it’s not secure putting the password in plainly like that. I’ll see if I can come up with something more secure and update later, but at least this should get you what you need to get started. Have a great week!

Edit: Added $EmailFrom based on JuanPablo’s comment

Edit: SMTP was spelled STMP in the attachments.
