Installation instructions

20  Installing GFI MailSecurity GFI MailSecurity for Exchange/SMTP
4. Setup will now ask you to select the mode that GFI MailSecurity will
use to retrieve the list of your email users. You must select one of the
following options:
 Yes, all email users are available on Active Directory. – Select
this option to continue installing GFI MailSecurity in Active
Directory mode. In this mode, GFI MailSecurity creates user-
based rules, for example Attachment Checking rules, based on the
list of users available in the Active Directory. This means that the
machine on which GFI MailSecurity is being installed must be
behind your firewall (for example, Mail Server) and must have
access to the Active Directory containing all your email users (i.e.,
the machine on which GFI MailSecurity is being installed must be
part of the Active Directory domain).
 No, I do not have Active Directory or my network does not
have access to Active Directory (DMZ). – Select this option to
continue installing GFI MailSecurity in SMTP mode. In this mode,
GFI MailSecurity will create user-based rules, for example
Attachment Checking rules, based on the list of email
users/addresses imported from your mail server. You must select
this mode if you are installing GFI MailSecurity on a machine that
does not have access to the Active Directory containing the
complete list of all your email users. This includes machines on a
DMZ or machines that are not part of the Active Directory Domain.
However, you can still choose this mode to install GFI MailSecurity
on machines that do have access to the Active Directory
containing all your email users.
Click Next to proceed with the installation.
