i Just came across this; useful if you need to send an email without a client from some random pc
$EmailFrom = “yourgmailadress@gmail.com”
$EmailTo = “destination@somedomain.com”
$Subject = “The subject of your email”
$Body = “What do you want your email to say”
$SMTPServer = “smtp.gmail.com”
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$SMTPClient.EnableSsl = $true
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential(“usr”, “pashttp://www.howtogeek.com/wp-content/uploads/2012/07/image304.pngs”);
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body)
