如何在 PowerShell 代码中发送带有附件的电子邮件？

Question

我正在尝试编写一个将电子邮件发送到指定电子邮件地址的 PowerShell 代码。当我运行代码时，它只会显示

+ $SMTPClient.Send <<<< ($EmailFrom, $EmailTo, $Attachment, $Subject, $Bod)
+ CategoryInfo          : NotSpecified: (:) [], MethodException
+ FullyQualifiedErrorId : MethodCountCouldNotFindBest

哦，顺便说一句，这是我的代码

$EmailFrom = “Myemail@outlook.com”
$EmailTo = “Someonesemail@gmail.com"
$Attachment = "(Filepath)"
$Subject = “Test”
$Bod = “Test”
$SMTPServer = “smtp.outlook.com”
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential(“Email”,“Pass”); $SMTPClient.Send($EmailFrom, $EmailTo, $Attachment, $Subject, $Bod)

请帮忙。我很痛苦

Answer 1

你应该先尝试这样的事情：

$Username  = "Myemail@outlook.com"
$EmailPassword = "YourRealPassword of your email"
$Attachment= "C:\Test.txt" # Example you can change its path here instead of "c:\Test.txt"
$EmailTo = "Someonesemail@gmail.com" 
$EmailFrom   = "Myemail@outlook.com" 
$Subject = "PowershellTest"
$Body= "PowershellTest"
$SMTPServer  = "smtp.outlook.com"  
$SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom, $EmailTo, $Subject, $Body) 
$Attachment  = New-Object System.Net.Mail.Attachment($Attachment)
$SMTPMessage.Attachments.Add($Attachment)
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($Username, $EmailPassword) 
$SMTPClient.Send($SMTPMessage)

编辑：使用 PowerShell 的 Send-MailMessage cmdlet

参考How to Send Email with Office 365 Direct Send and PowerShell

使用 PowerShell 的 Send-MailMessage cmdlet：

您首先需要定义一个 PowerShell PScredential 对象，然后提供Send-MailMessage 需要的所有参数。

# Get the credential
$credential = Get-Credential
## Define the Send-MailMessage parameters
$mailParams = @{
    SmtpServer                 = 'smtp.office365.com'
    Port                       = '587' 
    UseSSL                     = $true
    Credential                 = $credential
    From                       = 'sender@yourdomain.com'
    To                         = 'recipient@yourdomain.com', 'recipient@NotYourDomain.com'
    Subject                    = "SMTP Client Submission - $(Get-Date -Format g)"
    Body                       = 'This is a test email using SMTP Client Submission'
    Attachment                 = 'C:\Test.txt' # Here you can change your attachment
    DeliveryNotificationOption = 'OnFailure', 'OnSuccess'
}

## Send the message
Send-MailMessage @mailParams

当您运行上述代码时，您应该会收到一封由内部收件人 (yourdomain.com) 和外部域 (notyourdomain.com) 收到的带有附件的电子邮件。

重要提示：

如果你在用google的smtp发送邮件时遇到这个问题，你应该看看这个Can not send mail using smtp.gmail.com, port 587 from vbs script

您可以使用批处理和 powershell 发送电子邮件： 先把这段代码复制粘贴为

PS-Gmail-Sender.bat

@ECHO OFF
REM https://stackoverflow.com/questions/28605803/can-not-send-mail-using-smtp-gmail-com-port-587-from-vbs-script/28606754#28606754
Title Sending E-Mail with Gmail Less Secure Applications using Powershell and Batch
SET GmailAccount="%~1"
SET GmailPassword="%~2"
SET Attachment="%~3"
REM We write our Powershell script

EXIT
REM -----------------------------------------------------------------------------------------------------
:WritePS
SET PSScript=%temp%\temp_SendeMail.ps1
> "%PSScript%" (
    ECHO $Username  = $args[0]
    ECHO $EmailPassword = $args[1]
    ECHO $Attachment= $args[2]
    ECHO $EmailTo = $Username
    ECHO $EmailFrom  = $Username
    ECHO $Subject = "This email was sent from Powershell script into a batch file with Less Secure Application Enabled"   
    ECHO $Body= "Test Email Sending with a script"  
    ECHO $SMTPServer  = "smtp.gmail.com"  
    ECHO $SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom, $EmailTo, $Subject, $Body^) 
    ECHO $Attachment  = New-Object System.Net.Mail.Attachment($Attachment^)
    ECHO $SMTPMessage.Attachments.Add($Attachment^)
    ECHO $SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587^)
    ECHO $SMTPClient.EnableSsl = $true
    ECHO $SMTPClient.Credentials = New-Object System.Net.NetworkCredential($Username, $EmailPassword^) 
    ECHO $SMTPClient.Send($SMTPMessage^)
)
Exit /B
REM -----------------------------------------------------------------------------------------------------

其次，您可以从命令行调用此批处理文件，也可以将另一个批处理文件另存为 Sendit.bat 并通过双击执行以调用带有参数的第一个脚本PS-Gmail-Sender.bat

PS-Gmail-Sender.bat "Mygmail_Account@gmail.com" "MyGmail_Password" "D:\test\myFile.txt"
