Expand the co-operative with your server proper noun in the IIS vi Manager, right-click SMTP Virtual Server and open up its properties.

On the General tab, if necessary, select the IP accost on which the SMTP server should respond (if the server has multiple IP addresses), and check the selection Enable logging (in order to save information about all received emails to text log files).

Then go to the Access tab.

Hither click the Authentication button and brand sure that the Bearding access is enabled.

Get back to the Access tab and click the Connection button. Here yous can specify the IP addresses of devices that are immune to send emails through your SMTP relay. To do information technology, check the Only the list beneath and specify the list of IP addresses (subnets), don't forget about yourself (127.0.0.i).

Configure the same way the list of allowed IPs in the Relay settings (click the corresponding button). This department indicates which IP addresses (or subnets) can relay email through your SMTP server.

Note. As a general rule, it'southward worth to cheque this options and limit the listing of accepted devices with the range of IP addresses. Otherwise, your SMTP server may be used by spammers and other attackers as an open up relay for mass mailings.

Become to the Messages tab. Here the administrative e-mail service accost is specified, to which the copies of all NDR messages volition be send (Send copy of Not-Commitment Study to:).

To: admin@localdomain.com
Subject: Email test
This is the test email

The Windows SMTP server monitors new files appearing in this folder, and if a file is establish it volition read it contents and try to send an email with the given subject and trunk to the recipient specified in the To: line.
