This page is where you configure the LAN Forwarding feature of VPOP3
On this page you must press Submit after any changes for them to be saved.
The top section of the page shows the LAN Forwarding Rules which are defined.
To add a new rule, press the Add Row button.
In VPOP3 version 3 & 4 this will add a new row to the table which you then have to populate. See Edit a rule below for more details
In version 5 and later it brings up a window where you can enter the details
In the Addresses box you can enter one or more original email addresses which will be forwarded to the same server. Enter one address per line. You can use DOS style wildcards (* and ?) in the addresses. If you use ~ as the username part of the address (eg ~@domain.com) then this rule will only be checked after all other addresses (users, mappings, lists, specific LAN forwarding addresses etc) have been checked and haven't matched.
In the Target Server box you can enter the target SMTP server where messages for the specified addresses are to be sent
In the Rewrite Address box you can optionally enter an address which VPOP3 should redirect the messages to. If you use *@… then VPOP3 will use the original username from the recipient, but will change the domain. If you leave it blank, then VPOP3 will use the entire original recipient address

In the Target SMTP Server box you can enter the target SMTP server where messages for the specified addresses are to be sent
In the Target SMTP Port box you can enter the target SMTP server port where messages for the specified addresses are to be sent. This is usually port 25.
In the SMTP Username box type the username needed to log onto the target SMTP server (if any). Leave blank if authentication is not required.
In the SMTP Password box type the password needed to log onto the target SMTP server (if any). Leave blank if authentication is not required.
In the Rewrite Address box you can optionally enter an address which VPOP3 should redirect the messages to. If you use *@… then VPOP3 will use the original username from the recipient, but will change the domain. If you leave it blank, then VPOP3 will use the entire original recipient address
Select the rule(s) which you want to delete and press the Delete Row button.
To edit a rule, simply double-click on the value you want to change
The values are:
VPOP3 goes through the rules in order until one matches. This can be important if you use wildcards. You can reorder the rules by simply selecting the appropriate rule(s) in the table, and dragging them up or down to the correct position.
This is a new feature in VPOP3 version 5. If you press this button it lets VPOP3 check that an email address on an incoming SMTP message is valid at the onward server before deciding whether to accept or reject it. This can be useful if you are using VPOP3 as a backup SMTP server, so it will only accept mail for valid recipients if the final destination mail server is still active. If the final destination mail server does not respond, then VPOP3 will accept the mail in any case as it has no way of knowing whether the recipients are valid or not
Configure LAN Forwarding Server Address Verification for Wildcards
LAN Forwarding Thread Rules are useful if you have one copy of VPOP3 forwarding to several different mail servers. It lets you specify the maximum number of sending threads for each onward server.
Enter the rules as a set of space separated items, with each item being <server>-<max threads>
For instance 192.168.1.1-10 192.168.2.1:1025-5
will mean that VPOP3 will only send up to 10 messages at once to the 192.168.1.1 server, and up to 5 messages at once to the 192.168.2.1 server on port 1025.
The Maximum number of LAN Forwarding threads setting takes precedence, so if that was set to 5 in this example, then VPOP3 would only send up to 5 messages at once to the 192.168.1.1 server, and it would only send up to 5 messages at once overall, so it might send 3 messages to 192.168.1.1 and 2 messages to 192.168.2.1
Any servers which are not specified in these rules will have no limit (other than the overall maximum number of threads)
