email - Send-MailMessage : The SMTP server requires a secure connection. .. 服务器响应为 : 5. 5.1 需要身份验证。

Question

好吧，正如标题所说，我在尝试通过 PowerShell 发送电子邮件时收到此错误:

Send-MailMessage:SMTP 服务器需要安全连接或客户端未通过身份验证。服务器响应为:5.5.1 需要身份验证。

我已经查看了许多与同一问题相关的问题。但我似乎无法让我的脚本工作:

    #Email alerts when a user gets locked out
##############################################################################
$pass = Get-Content .\securepass.txt | ConvertTo-SecureString -AsPlainText -Force
$name = "sender@gmail.com"
$cred = New-Object System.Management.Automation.PSCredential($name,$pass)
##############################################################################
$From = "sender@gmail.com"
$To = "recipient@domain.org"
$Subject = "User Locked Out"
$Body = "A user has been locked out of his/her account."
$SMTPServer = "smtp.gmail.com"
$SMTPPort = "587"

Send-MailMessage -From $From -to $To -Subject $Subject `
-Body $Body -SmtpServer $SMTPServer -port $SMTPPort `
-Credential $cred -UseSsl
##############################################################################

我已经从将运行脚本的机器登录到 Gmail 帐户。我还从 Google 客户经理处启用了访问安全性较低的应用程序。如果我使用 -Credential (Get-Credential) 提示输入凭据而不是调用 $cred 变量，我确实可以正常工作。

有什么我想念的吗？

谢谢，丹

如果文件包含加密密码，最好像这样读取它(不带参数 -AsPlainText 和 -Force):

$pass = Get-Content .\securepass.txt | ConvertTo-SecureString

演示:

PS C:\> $sec = 'foobar' | ConvertTo-SecureString -AsPlainText -ForcePS C:\> $secSystem.Security.SecureStringPS C:\> $txt = $sec | ConvertFrom-SecureStringPS C:\> $txt01000000d08c9ddf0115d1118c7a00c04fc297eb01000000615ce070639b9647a5e05d42b41d3730000000000200000000001066000000010000200000001614c19281e7c0b076cceb38e284b0f18bc0d813ea40ed055dde96fd9ccb6977000000000e8000000002000020000000a10c7019eb224c3c6387ba03bcd94993a50e0c468248284bbce4d235b11f1b94100000002421a5d7102de13c46ccc1dbc4921287400000000412332ecb500828f4403f3e225089c629369744bad62609b528ed0a7318abf512c9b6a8884c43b3adc8a13d5d21a9ed27e56702bcc7db094da9d9d4c02dfa74PS C:\> $sec2 = $txt | ConvertTo-SecureStringPS C:\> $sec2System.Security.SecureStringPS C:\> $cred = New-Object Management.Automation.PSCredential 'foo', $sec2PS C:\> $cred.GetNetworkCredential().Passwordfoobar

请注意，安全字符串的加密与用户和主机加密有关，这意味着您无法在另一台主机上或作为另一用户解密安全字符串。
