Checking if the MX record for your domain is set correctly 

1.  Open command prompt. Type nslookup 

2.  Now type  set type=mx  

3.  Enter your mail domain. 

4.  The MX record should return a single IP. This IP must be the IP of 

the machine on which GFI MailSecurity is installed! 

Checking the MX record of your domain 

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 

Step  1:

  Run  GFI  MailSecurity  set up  by  double clicking  the  file 

MailSecurity.exe 

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.

Step 2:

 Confirm the License agreement. 

Step  3:
