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 the IIS SMTP inbound connection of your mail relay server by
sending an email from an external account to an internal user (you
can use web-mail, for example MSN Hotmail, if you do not have an
external account available). Verify that the email client received the
email.
2. Test the IIS SMTP outbound connection of your mail relay server by
sending an email to an external account from an email client. Verify
that the external user received the email.
NOTE: Instead of using an email client, you can send email manually
through Telnet. This will give you more troubleshooting information.
