1) Adding the SMTP Server

– Open Server Manager
– select “Features”
– click “Add Features” and check “SMTP Server”
NOTE: The SMTP Server feature might require the installation of additional role services and features. Click Add Required Role Services to proceed with installation.
– click Next to configure any required role services and features
– click Install to start the installation.

2) Setting up SMTP

– Open IIS
– click on the server, open the “features view” (at the bottom) – double click “SMTP E-mail” probably under ASP.NET
– Enter the from address
– select Deliver to SMTP server
– check “Use localhost”
– I recommend putting Authentication settings, specify credentials! (click the ellipsis “…” to enter a username and password)

3) Configuring SMTP

– Open command prompt
– type cd \Windows\System32\inetsrv then hit return
– type all on one line. This is CASE SENSITIVE. Replace the values for /from (e.g. “you@yourdomain.com”) and the network port, host, userName, and password.

appcmd set config /commit:WEBROOT /section:smtp /from:you@yourdomain.com /deliveryMethod:Network /network.port:25 /network.defaultCredentials:True /network.host:localhost /network.userName:your_username /network.password:your_password

I used the from email as the username.

4)Configure PHP.ini


SMTP=localhost
sendmail_from=you@yourdomain.com
smtp_port=25


5) Enable Relay for localhost:

– open iis 6.0 (even if you are on iis7, you should have iis6 on your machine!)
– right click the virtual server

Restricting who can send!

– select the “access” tab
– click “connection” and Select “Only the list below”
– add only your server’s i.p. address. The dns lookup can help, type “localhost” or the name of your machine.
– click “ok” then click “apply”
– click “Relay…”
– do the same as above (set to “Only the list below” and add your machine’s i.p. address)
– I would un-check the ability for remote servers to relay, even if they authenticate… in case some bot brute forces in and then uses your server to send spam.

6) SEND MAIL WITH PHP!!!

Test it out. I use PHP mailer.
(use one of your emails to see if you actually get it. A success does NOT mean it will reach the user!)

WordWrap = 50; // set word wrap to 50 characters
$email->isSMTP();
$email-->Host = 'localhost';
$email->Port = 25; // 587 and 465 are also common
$email->Username = 'you@yourdomain.com';
$email->Password = 'your_password';
$email->Subject = 'Hello World of SMTP';
$email->Body = 'This is a test from IIS and PHP';
$email->AddAddress('your_other_email@genericdomain.com','Your Name');
$email->From = 'you@yourdomain.com';
$email->FromName = 'Your Website';

if($email->send()){
echo 'ok! I did it! I set up an SMTP server (for sending only)!';
}
else
{
echo 'Dang... all that work and I\'m still here.
'.$email->ErrorInfo;
}


Good luck! Now make sure you add SPF records for all of your domains. 🙂
