In PowerShell how do you configure smtpserver:

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

PS code:

$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

No matter if I use for SmtpServer: 'smtp.email.com' or $IPsmtp I still get the same result.

This ps code is missing the credentials for'smtp.email.com'.  It has a username and password associated with it but nowhere to enter it.

error code:
