Question

我正在尝试发送电子邮件，但我收到语法错误：

$fromaddress = "abc@a.com" 
$toaddress = @('def@a.com>', 'ghi@a.com>')
$bccaddress = @('sl@a.com') 
#$CCaddress = @('la@a.com>') 
$Subject = "BAKUP REPORT FOR Instances " 
$body = get-content C:\body.txt 
$attachment = @("C:\result.text", "C:\result.csv", "C:\object.text", "C:\object.csv") 
$smtpserver = "smtp.a.com" 

$message = new-object System.Net.Mail.MailMessage 
$message.From = $fromaddress 
$message.To.Add($toaddress) 
#$message.CC.Add($CCaddress) 
$message.Bcc.Add($bccaddress) 
$message.IsBodyHtml = $True 
$message.Subject = $Subject 
$attach = new-object Net.Mail.Attachment($attachment) 
$message.Attachments.Add($attach) 
$message.body = $body 
$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$smtp.Send($message)

我收到以下错误。

怎么样：

$fromaddress = "abc@a.com" 
$toaddress = @('def@a.com>', 'ghi@a.com>')
$bccaddress = @('sl@a.com') 
#$CCaddress = @('la@a.com>') 
$Subject = "BAKUP REPORT FOR Instances " 
$body = get-content C:\body.txt 
$attachment1 = @("C:\result.text") 
$attachment2 = @("C:\result.csv",) 
$attachment3 = @("C:\object.text") 
$attachment4 = @("C:\object.csv") 
$smtpserver = "smtp.a.com" 

$message = new-object System.Net.Mail.MailMessage 
$message.From = $fromaddress 
$message.To.Add($toaddress) 
#$message.CC.Add($CCaddress) 
$message.Bcc.Add($bccaddress) 
$message.IsBodyHtml = $True 
$message.Subject = $Subject 
$attach = new-object Net.Mail.Attachment($attachment1) 
$message.Attachments.Add($attach) 
    $attach = new-object Net.Mail.Attachment($attachment2) 
$message.Attachments.Add($attach) 
    $attach = new-object Net.Mail.Attachment($attachment3) 
$message.Attachments.Add($attach) 
    $attach = new-object Net.Mail.Attachment($attachment4) 
$message.Attachments.Add($attach) 

$message.body = $body 
$smtp = new-object Net.Mail.SmtpClient($smtpserver) 
$smtp.Send($message)

您的上一个错误可能与身份验证有关。最好搜索＆＃34;通过telnet发送电子邮件＆＃34;做快速测试。使用How to send email using simple SMTP commands via Gmail?作为参考。

附上代码以包含身份验证：

----> ADD AFTER >> $smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort);
$smtp.EnableSSL = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, 
      $Password);

我更喜欢使用Send-MailMessage，因为它具有更好的语法Net.Mail，您还可以使用Splatting使其更易于阅读：

$messageParameters = @{                        
    From = "abc@a.com"
    To = "def@a.com>", "ghi@a.com>"
    Bcc = "sl@a.com"
    #Cc = "la@a.com>"

    Subject = "BAKUP REPORT FOR Instances"
    Body = Get-Content C:\body.txt
    Attachments = "C:\result.text", "C:\result.csv", "C:\object.text", "C:\object.csv"
    SmtpServer = "smtp.a.com"
}                        
Send-MailMessage @messageParameters -BodyAsHtml

您可能还需要为身份验证和/或SSL指定凭据，具体取决于您的SMTP服务器。
