how to configure your e-mail server to route all e-mail messages via Impactia
(The following explanation will refer specifically to the implementation on a Microsoft Exchange 2003/2007 Servers, however it may be implemented on Email servers of other types or versions by performing the equivalent actions described.)
Sending outbound email via the Impactia Server requires configuring at least two SMTP Connectors.
-
Create a Default SMTP Connector (using Creating SMTP connector in Microsoft Exchange 2003 Server / Creating SMTP connector in Microsoft Exchange 2007/2010 Server).
-
Create an Impactia SMTP Connector (using Creating SMTP connector in Microsoft Exchange 2003 Server / Creating a SMTP connector in Microsoft Exchange 2007/2010 Server).
The ‘Cost’ field in each of these two SMTP Connectors is the precedence/failover mechanism Exchange uses to decide via which connector to route a message (a lower number means a higher priority).
After performing the instructions above, the ‘Cost’ of each connector is as follows; ‘Default SMTP Connector’ cost = 1 ‘Impactia’ connector cost = 10. i.e. the Exchange server will always try to send outbound messages via the Default SMTP Connector first.
When you are ready to start routing ALL your company email via the Impactia Server, change the Cost attribute for each of the two connectors such that the Impactia Connector has a LOWER number than that of the Default SMTP Connector. (e.g. change the cost of the Default SMTP Connector to ‘20’).
how to configure your e-mail server to route SPECIFIC e-mail via Impactia
(The following explanation will refer specifically to the implementation on a Microsoft Exchange 2003 Server, however it may be implemented on Email servers of other types or versions by performing the equivalent actions described below.)
Follow the instructions in the document:
-
-
Change the Cost attribute of both connectors, such that the Default SMTP connector has a Lower cost than that of the Impactia Connector.
.
-
-
Create an Impactia Failover SMTP Connector (using Creating an SMTP connector in Microsoft Exchange 2003 Server).
.
-
Configure Delivery Restrictions for all 3 connectors:
.
-
Under the properties of the ‘Default SMTP connector’, Click on the “Delivery Restrictions” tab, and add the individual users or groups to the “Reject messages from” section, in the bottom half of the screen
-
Under the properties of the ‘Impactia Connector’, Click on the “Delivery Restrictions” tab, and add the individual users or groups to the “Accept messages from” section, in the top half of the screen.
-
Under the properties of the ‘Impactia Failover’ SMTP connector, Click on the “Delivery Restrictions” tab, add the individual users or groups to the “Accept messages from” section, in the top half of the screen. Remove any users from the “Reject messages from” section.
.
-
Enable ‘Exchange Connector Restriction Checking’ in the registry
(as per Microsoft Article:http://support.microsoft.com/default.aspx?scid=kb;en-us;Q277872)
.
-
Start Registry Editor (Regedt32.exe).
.
-
Locate and click the following registry key: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Resvc/Parameters/
.
-
On the Edit menu, click Add Value, and then add the following registry value:
-
Value Name: CheckConnectorRestrictions
-
Data Type: REG_DWORD
-
Radix: Hexadecimal
-
Value: 1
.
-
Quit Registry Editor.
.
-
Restart ALL Microsoft Exchange services and the Simple Mail Transfer Protocol (SMTP) services for this change to take effect.
