Chapter 6 – RouteFinder Software
Proxy > SMTP Proxy
When Status is checked, the screen expands to display the following fields:
Accepted Incoming Domains
All the domains for which the SMTP Proxy can accept emails must be listed here. The domain for which
emails are accepted must be registered with the DNS server. Thus, the SMTP Proxy accepts only emails
which are addressed to the domains listed here.
Domains will be listed in the drop-down box from which they can be deleted, if desired.
Mail Relay
All the networks that can use the SMTP Proxy as a relay agent are configured here. A list of the various
networks configured using this software is displayed. You can add networks that can use the SMTP proxy
as a relay agent by using the Add button. All other networks not included in this list can send emails to
only those domains in the Accepted Incoming Domains list. The IP address of the mail server needs to be
added in the list of relay networks.
Add SMTP Routes
The SMTP Proxy decides on the path or the route to be taken for any domains based on the SMTP
Routes configuration. Thus, the domain name and the IP address of the MTA (Mail Transfer Agent) to
which mails are destined to this domain are to be forwarded are listed here.
Example: xyz.com:192.168.1.34. Any email to domain xyz.com is forwarded to 192.168.1.34, which is the
IP address of an MTA. If the SMTP route is not mentioned for a domain, then a DNS-lookup decides
where this email is to be forwarded or else a default route can be specified so that email to any domain is
forwarded to the default gateway. Example: 192.168.1.10.
Domain and Host
The fully qualified Domain Name and Host of the SMTP Proxy must be entered here.
Main SMTP Screen Continued
Queue Cleanup
Click the Clean button to delete emails held in the relay agent's mail queue. All mails waiting to be
delivered will be cleaned up. This option is to be used with extreme care.
Virus Protection – SMTP Virus Protection
Enables/disables virus scanning for SMTP traffic that passes through the RouteFinder. Both incoming and
outgoing emails are scanned, if they are sent via the SMTP proxy. If a valid virus license scanner license
key is not entered, this option will not be displayed.
An anti-virus license must be purchased from Multi-Tech in order to use virus protection, and the license
can be uploaded to the RouteFinder from the Administration > License Keys screen.
Remote SMTP Virus Quarantine – Remote SMTP Virus Quarantine Status
Check the Remote SMTP Virus Quarantine Status box to activate the remote quarantining of SMTP
virus emails. If activated, then local quarantining no longer exists.
Action Taken on Virus Emails
Change Action on Infected Mails: Select the action to be taken on infected emails for SMTP traffic.
If the action selected is Notify, options to send the information to the administrator / sender / recipient will
be displayed. Notification regarding infected mails will be send based on these settings.
If the action is Block, the mail will be silently dropped.
In both cases, the infected emails will be stored in the virus quarantine folder of the RouteFinder. The
administrator can view the emails, delete them, or forward them to a specified email ID.
Click the Save button after a Change Action.
