How to use SMTP authentication within web scripts

How do I add SMTP Authentication in my scripts


This is different for each type of mailing component, below is the code you need to add to your scripts.

ASPMail 4:
No longer supported, use ASPEmail 5, to change to ASPMail 5 from ASPMail, in your script do the following:

Find: Set Mailer = Server.CreateObject("SMTPsvg.Mailer")
Replace with: Set Mailer = Server.CreateObject("Persits.MailSender")

ASPEmail 5:
Find the line of code that contains the Mail Server Host address ie Mailer.Host = yourHost or yourHost = for example. then on the next line add:
Mail.Username = ""

Mail.Password = "Your-email-login-password"

This will fix the problem for ASPEmail 5.

JMail Pro 4.5:
Add the following code to your mailer script:
Message.MailServerUserName = ""

Message.MailServerPassword = "Your-email-login-password"

This will fix the problem for Jmail.


For CDOSYS, this is a little bit more complex, see
for an example script including Authentication.


PHPMail is not supported on Windows, however you can use a PHP SMTP script which will work, see

For PHPMailer scripts try editing your script to add the SMTP options like below:

$mail = new PHPMailer();
$mail->IsSMTP(); // send via SMTP
$mail->Host = "mail.your-domain"; // SMTP servers
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username =
you@your-domain; // SMTP username
$mail->Password = "POP3-Password"; // SMTP password
$mail->Port = 25;
