如何将凭据传递给Send-MailMessage命令以发送电子邮件

Question

我将凭据传递给Send-MailMessage命令时遇到了困难

这就是我正在运行的:

Send-MailMessage -smtpServer smtp.gmail.com -from 'myself@gmail.com' `
    -to 'myself@gmail.com' -subject 'Test' -attachment C:\CDF.pdf

它错误显示在消息下方,这显然是因为我没有通过我的gmail凭据

Send-MailMessage : The SMTP server requires a secure connection or the client was not
authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first.

我google了一下,也浏览了手册页,Send-MailMessage发现需要传递"-credential"参数.

我的问题是:怎么样？

我尝试使用Get-Credentials,如下所示:

$mycredentials = Get-Credential

然后在弹出的框中输入我的用户名和密码.

然后我运行以下命令:

Send-MailMessage -smtpServer smtp.gmail.com -credentail $mycredentials `
  -from 'myself@gmail.com' -to 'myself@gmail.com' -subject 'Test' -attachment C:\CDF.pdf

并且它仍然以完全相同的错误失败.

所以我需要你们帮助我们如何将我的证书传递给Send-MailMessage命令.我了解了PScredentials,但不完全确定它是什么以及如何在这种情况下使用它.

我发现这个博客网站:Adam Kahtava
我也发现了这个问题:send-mail-via-gmail-with-powershell-v2s-send-mailmessage
问题是,它们都没有解决你的需求(附件用密码),所以我做了两者的组合并得出了这个:

$EmailTo = "myself@gmail.com"
$EmailFrom = "me@mydomain.com"
$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)

既然我喜欢为事物做功能,而且我需要我能得到的所有练习,我继续写下这个:

Function Send-EMail {
    Param (
        [Parameter(`
            Mandatory=$true)]
        [String]$EmailTo,
        [Parameter(`
            Mandatory=$true)]
        [String]$Subject,
        [Parameter(`
            Mandatory=$true)]
        [String]$Body,
        [Parameter(`
            Mandatory=$true)]
        [String]$EmailFrom="myself@gmail.com",  #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

要调用它,只需使用此命令:

Send-EMail -EmailTo "Myself@gmail.com" -Body "Test Body" -Subject "Test Subject" -attachment "C:\cdf.pdf" -password "Passowrd"

我知道把密码简单地放在那里是不安全的.我会看看我是否可以提出更安全的东西并在以后更新,但至少这应该可以帮助您了解入门所需的内容.祝你度过愉快的一周!

Answer 2

我花了一段时间来整合所有内容,使其有点安全,并让它与Gmail一起使用.我希望这个答案能节省一些时间.

使用加密的服务器密码创建文件:

在Powershell中,输入以下命令(将myPassword替换为您的实际密码):

"myPassword" | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "C:\EmailPassword.txt"

创建一个powershell脚本(例如sendEmail.ps1):

$User = "usernameForEmailPassword@gmail.com"
$File = "C:\EmailPassword.txt"
$cred=New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, (Get-Content $File | ConvertTo-SecureString)
$EmailTo = "emailTo@yahoo.com"
$EmailFrom = "emailFrom@gmail.com"
$Subject = "Email Subject" 
$Body = "Email body text" 
$SMTPServer = "smtp.gmail.com" 
$filenameAndPath = "C:\fileIwantToSend.csv"
$SMTPMessage = New-Object System.Net.Mail.MailMessage($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 
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password); 
$SMTPClient.Send($SMTPMessage)

使用任务计划程序自动执行:

使用以下命令创建批处理文件(例如,emailFile.bat):

powershell -ExecutionPolicy ByPass -File C:\sendEmail.ps1

创建任务以运行批处理文件.注意:您必须使用与加密密码相同的用户帐户运行任务!(Aka,可能是登录用户)

就这样; 您现在可以使用Windows任务计划程序和Powershell自动执行和计划发送电子邮件和附件.没有第三方软件和密码不会以纯文本形式存储(虽然已授予,但也不是非常安全).

Answer 3

所以..这是SSL问题.无论我做什么都是绝对正确的.只是我没有使用ssl选项.所以我在原始命令中添加了"-Usessl true"并且它有效.

Answer 4

PSH> $ cred = Get-Credential

PSH> $ cred | Export-CliXml c:\ temp\cred.clixml

PSH> $ cred2 = Import-CliXml c:\ temp\cred.clixml

这会将其与您的SID和机器的SID进行哈希处理,因此该文件在任何其他计算机或其他任何人的手中都无法使用.

Answer 5

这是一个简单的Send-MailMessage带有用户名/密码的例子

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)
Send-MailMessage -SmtpServer mysmptp -Credential $cred -UseSsl -From 'sender@gmail.com' -To 'recipient@gmail.com' -Subject 'TEST'

Answer 6

除了 UseSsl 之外，您还必须包括 smtp 端口 587 才能使其工作。

Send-MailMessage -SmtpServer smtp.gmail.com -Port 587 -Credential $credential -UseSsl -From 'yyy@gmail.com' -To 'xxx@email.com' -Subject 'TEST'
