Installing GFI MailSecurity on a mail relay server
Figure 2 - Installing GFI MailSecurity on a mail gateway/relay server
When installing on a separate server (i.e., on a server which is not
your mail server), you must first configure that machine to act as a
gateway (also known as “Smart host” or “Mail relay” server) for all your
email. This means that all inbound email must pass through this
machine for scanning before being relayed to the mail server for
distribution (i.e., it must be the first to receive all emails destined for
your mail server). The same applies for outbound emails: The mail
server must relay all outgoing emails to the gateway machine for
scanning before they are conveyed to the external recipients via
Internet (i.e. it must be the last 'stop‟ for emails destined for the
Internet). In this way, GFI MailSecurity checks all your inbound and
outbound mail before this is delivered to the recipients.
NOTE 1: You must install GFI MailSecurity in SMTP Gateway mode if
you are running Lotus Notes or another SMTP/POP3 server.
NOTE 2: If you are running a Windows NT network, the machine
running GFI MailSecurity can be separate from your Windows NT
network GFI MailSecurity does not require Active Directory when
installed in SMTP mode.
