PowerShell配置smtpserver

Question

在PowerShell中，如何配置smtpserver：

ping "stmp.email.com" = “xxx.xx.xx.xxx”
$smtpServer = “xxx.xx.xx.xxx” or "stmp.email.com"????????

PS代码：

$IPsmtp = 'xxx.xx.xx.xxx'
$PlainPassword = "adminpassword"
$SecurePassword = $PlainPassword | ConvertTo-SecureString -AsPlainText -Force
$Username = "MYSITE\Administrator"
$Credentials = New-Object System.Management.Automation.PSCredential    -ArgumentList $Username, $SecurePassword
$mailprops=@{
    Subject = 'This Subject'
    Body = 'The Body and the subBody'
    To = 'emailto@mail.com'
    From = 'emailfrom@email.com'
    SmtpServer = 'smtp.email.com'
}
Send-MailMessage $mailprops -Credential $Credentials

无论我是否使用SmtpServer：'smtp.email.com'或$ IPsmtp，我仍然会得到相同的结果。

此ps代码缺少'mmp.email.com'的凭据。它有一个与之关联的用户名和密码，但无处输入。

错误代码：
