[windows] sending mail from Batch file

We have a script to backup files. After the backup operation is over, we would like to send a report as an email notification to some of our email addresses.

How could this be done?

There are multiple methods for handling this problem.

My advice is to use the powerful Windows freeware console application SendEmail.

sendEmail.exe -f [email protected] -o message-file=body.txt -u subject message -t [email protected] -a attachment.zip -s smtp.gmail.com:446 -xu gmail.login -xp gmail.password

You can also use a Power Shell script:

$smtp = new-object Net.Mail.SmtpClient("mail.example.com")

if( $Env:SmtpUseCredentials -eq "true" ) {
    $credentials = new-object Net.NetworkCredential("username","password")
    $smtp.Credentials = $credentials
}
$objMailMessage = New-Object System.Net.Mail.MailMessage
$objMailMessage.From = "[email protected]"
$objMailMessage.To.Add("[email protected]")
$objMailMessage.Subject = "eMail subject Notification"
$objMailMessage.Body = "Hello world!"

$smtp.send($objMailMessage)

We use blat to do this all the time in our environment. I use it as well to connect to Gmail with Stunnel. Here's the params to send a file

blat -to [email protected] -server smtp.example.com -f [email protected] -subject "subject" -body "body" -attach c:\temp\file.txt

Or you can put that file in as the body

blat c:\temp\file.txt -to [email protected] -server smtp.example.com -f [email protected] -subject "subject"

PowerShell comes with a built in command for it. So running directly from a .bat file:

powershell -ExecutionPolicy ByPass -Command Send-MailMessage ^
    -SmtpServer server.address.name ^
    -To [email protected] ^
    -From [email protected] ^
    -Subject Testing ^
    -Body 123

_{NB -ExecutionPolicy ByPass is only needed if you haven't set up permissions for running PS from CMD}

_{Also for those looking to call it from within powershell, drop everything before -Command [inclusive], and ` will be your escape character (not ^)}

Blat:

blat -to [email protected] -server smtp.example.com -f [email protected] -subject "subject" -body "body"

bmail. Just install the EXE and run a line like this:

bmail -s myMailServer -f [email protected] -t [email protected] -a "Production Release Performed"
