SMTP/POP3 mail server
Configure your mail server to route all inbound and outbound email through GFI MailEssentials. In the
configuration program of your mail server, use the option to relay all outbound email via another mail
server (this option is usually called something similar to Forward all messages to host. Enter the
computer name or IP of the machine running GFI MailEssentials. Save the new settings and restart
your mail server.
Step 6: Update your domain MX record to point to mail relay server
Update the MX record of your domain to point to the IP of the new mail relay server. If your DNS
server is managed by your ISP, ask your ISP to update the MX record for you.
NOTE
If the MX record is not updated, all emails will be routed directly to your email server -
hence bypassing GFI MailEssentials.
Verify that MX record has been successfully updated
To verify whether MX record is updated:
1. From command prompt key in nslookup and hit Enter.
2. Key in set type=mx and hit Enter.
3. Specify your mail domain name and hit Enter.
The MX record should return the IP addresses of the mail relay servers.

Before proceeding to install GFI MailEssentials, verify that your new mail relay server is working
correctly.
