I can't remember where is nabbed it from, but I use the following:
Function Mailer
{
$emailTo = ""
$emailFrom = ""
$subject="It's broken, damn it"
$smtpserver=""
$smtp=new-object System.Net.Mail.SmtpClient($smtpServer)
$Message = @"
Insert a useful/meaningful message here.
"@
}
Mailer
Last line calls the function (duh for you, but a visitor here might not know).
