Example of SMTP Proxy
An entry Company.com covers all further sub-domains; for example, subsidiary1.Company.com
and subsidiary2.Company.com. The RouteFinder must be the MX (Mail Exchanger) for
Company.com. Incoming emails to non-registered domains are rejected (except for senders listed in
Mail relay for below). Confirm every registered domain by clicking the Add button. The domains are
entered into a window from which the entered domains can be deleted again at any time.
Mail relay for
Select all the networks from the select menu that are allowed to use the SMTP proxy on the
RouteFinder. Networks not entered here can only use the SMTP proxy to send emails to
the above listed domains. Confirm every selected network by clicking the Add button.
Note: If you assign Any, then everybody connected to the Internet can use your SMTP
proxy for SPAM purposes.
SMTP Routes
Determine the MTA (Mail Transfer Agent) to which each incoming domain is forwarded. The
MTA is determined by its IP address. You can also configure the forwarding of email into
your internal messaging system here. If you want to use the SMTP proxy as the SMTP
relay (also often called "SmartHost“) for your internal email server, configure it to use the
internal address of your RouteFinder system as a relay. However, for this to work, the IP
address of your internal email server must have been entered in the Mail relay for select
menu. (Remember to insert the forwarding of the domains to your internal email server.)
All outgoing mail is then forwarded via the SMTP proxy of the RouteFinder.
All settings are immediately active and are preserved after leaving the Proxies > SMTP
menu.
