Step 7: Test your new mail relay server!
Before you proceed to install GFI MailSecurity, verify that your new
mail relay server is working correctly.
1. Test IIS 5 SMTP inbound connection of your mail relay server by
sending a mail from an external account to an internal user (you can
use hotmail, if you don't have an external account available). Verify
that the mail client received the email.
2. Test IIS 5 SMTP outbound connection of your mail relay server by
sending a mail to an external account from a mail client. Verify that the
external user received the email.
Note: Instead of using an email client, you can use Telnet and
manually send an email. This will give you more troubleshooting
information. Here is the link to the Microsoft KB article how to do it:
Step 8: Running GFI MailSecurity set up
Run GFI MailSecurity set up by double clicking the file
on the SMTP relay machine. GFI MailSecurity will
also prompt you to check for a later GFI MailSecurity version. We
recommend you do this and always use the latest version.
