SMTP Location allows you to define different locations (Home, Office,
Customer-office, ...) by network rules (IP addresses and network masks),
and associate a default SMTP server per location.
SMTP Control will calculate location based on user rules and propose
the default server in the swap list.
The above picture shows The discovered IP addresses of the system and
the calculated location. If you have just change some of the location
parameters (see other tabs) you can trigger a relocation to check the
modifications. When Applying and Closing the option window, SMTP Control
will automatically trigger a relocation calculation.
New Locations can be added with the tab "Locations Definition".
To add a new location, click on "Add Location" button. A default
name for the location is proposed, you should change it to something easy
to understand for you.
To define the location you have to add at least one IP rule. Click on
"Add" near the "IP rules" selection list and give
one, two or three IP addresses with their network mask to define this
location. Most of the location would have only one IP address. Current
version only support masks with values 8,16,24,32. If you don't know which
mask to choose, prefer 24 value. Network mask aspect will be more detailled
in a futur documentation.
You can also use 2 or 3 addresses in situation where your system has for
exemple an IP address for the local network (my home network) and an IP
address for a VPN connection to the enterprise. Have 2 IP addresse will
give you the ability to define a location like "Office connection
If your location can have different network properties, then you can
define several separate IP rules. For exemple "Office" can be
for you the "Office building in Paris" using IP 10.10.2.0/24
or the "Office building in New-York" using IP 192.168.20.0/24.
When SMTP Control detect any one of these IP it will know that the location
is "Office". Without the need for 2 locations.
To finish the location definition you have to select which SMTP server
will be the location default in the drop down menu.
To remove a location, select the location in the dop down menu and click
A new Location can also be created directly from the tool menu :
By doing that SMTP Control will automatically use the current IP address
as rule for defining the new location.
By the menu you can also correct a location discovery. By doing that
the IP addresses will be added in a new rule for the selected location.
Locate the default SMTP server based on location need to be configured
per email account. To enable this feature you need to select which email
account allow this feature by using the "Location per Account"
Note : By default no email account has this feature enabled. Which is
not a good default behavior ... (realize this while writing the doc).
Expect a different default behavior in next realize ...
"Ignored IP Addresses" tab is an advanced configuration. For
those who are using tools like VmWare workstation or server, you will
have static IP addresses all the time configured on your system for virtual
networking. You will need to ignore these IP addresses to have better
accuracy in the location detection. You can define the IP addresses or
network that SMTP Control has to ignore while doing the location calculation.
