使用加密密码发送邮件失败

Question

我正在尝试在发送电子邮件的脚本中使用存储的加密密码，但我不断收到错误消息：

send-mailmessage : The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM [DM6PR66666019.namprd456.prod.outlook.com]

我使用以下代码创建了文本文件：

$passwordtostore = 'NotTheRealPasswordgv8z6VHnPfDd8zc'
$secureStringPWD = $passwordtostore | ConvertTo-SecureString -AsPlainText -Force
$secureStringText = $secureStringPWD | ConvertFrom-SecureString
Set-Content "c:\temp\scriptsencrypted_password1.txt" $secureStringText

我使用以下方式导入密码：

$passwordFile = "c:\temp\scriptsencrypted_password1.txt"
$password = Get-Content $passwordFile | ConvertTo-SecureString

这是我正在使用的发送邮件功能：

function SendMail($ToEmails,$FromEmail,$Subj,$Body,$UserName,$Password){
    $cred = New-Object System.Management.Automation.PSCredential $UserName,$Password

    $MailParams=@{"from"=$FromEmail; "to"=$ToEmails;"body"=$Body;"subject"=$Subj;"smtpserver"="smtp.office365.com"}

    send-mailmessage @MailParams -Credential $cred -UseSsl $true -port 587
}

调用函数的代码如下：

$alertEmail = "me.stillme@mydomain.com"
$username="psemail@mydomain.com"
$passwordFile = "c:\temp\scriptsencrypted_password1.txt"
$password = Get-Content $passwordFile | ConvertTo-SecureString
$credential = New-Object System.Management.Automation.PsCredential($username, $password)

Import-Module -Name "..\SendMail.psm1"

... Doing some stuff

SendMail $alertEmail $username "This is the subject" "this is the body" $credential.UserName $credential.Password

Answer 1

就我个人而言，我不明白为什么要在需要为 Send-MailMessage cmdlet 导入的模块中创建一个函数。这使得事情变得更难使用。

此外，您似乎在函数内部切换电子邮件地址。

无论如何，创建凭据时出现问题，将其拆分为用户名和（安全）密码以作为参数发送给函数，然后将它们重新组合到其中的凭据对象中。

为什么不跳过那个模块函数而简单地做：

$password = Get-Content 'c:\temp\scriptsencrypted_password1.txt' -Raw | ConvertTo-SecureString -AsPlainText -Force
$credential = New-Object System.Management.Automation.PsCredential('YourLoginName', $password)
$MailParams=@{
    From       = 'me.stillme@mydomain.com'
    To         = 'psemail@mydomain.com'
    Body       = "this is the body"
    Subject    = "This is the subject"
    SmtpServer = 'smtp.office365.com'
    Port       = 587
    UseSsl     = $true
    Credential = $credential
}

Send-MailMessage @MailParams

这将使您的脚本更加readable/maintainable

Answer 2

我在上面的代码中发现了两个问题：

密码中未转义的 $。
一旦我将“-NoNewline”添加到设置内容中，它就开始工作了。

因此，要创建加密文件：

$passwordtostore = "7K9CBgvc4rttvfctrsef6PVHqnP6fDdwhatevervtfdscttzSc"
$secureStringPWD = $passwordtostore | ConvertTo-SecureString -AsPlainText -Force
$secureStringText = $secureStringPWD | ConvertFrom-SecureString
Set-Content "D:\Powershell Scripts\encrypted.hash" $secureStringText -NoNewline

然后检索密码并在凭据中使用它：

$password = Get-Content $passwordFile -Raw | ConvertTo-SecureString
$credential = New-Object System.Management.Automation.PsCredential($username, $password)

这不是问题的根源，但我确实执行了@Theo 的建议：使用 send-mailmessage。
