 +======Using VPOP3 with Microsoft Exchange Server======
 +You can link VPOP3 to Exchange Server, so that Exchange Server sends outgoing mail through VPOP3 and VPOP3 sends any incoming mail directly to Exchange Server.
 +
 +You should first of all set up VPOP3 to send and receive Internet email as described in the online help.
 +
 +=====Exchange Server 5.5=====
 +====VPOP3 and Exchange Server on the same PC====
 +===Changing the Exchange Server SMTP port===
 +As both VPOP3 and Exchange Server are on the same computer, you will need to change the TCP/IP port assignments for the SMTP service in Exchange Server. You should NOT change the SMTP service port in VPOP3 as you cannot change the port which Exchange Server will forward to, but you can change the port which VPOP3 will forward to.
 +
 +On the Exchange Server computer, edit the file ''​\System32\drivers\etc\services''​ using Notepad.
 +
 +Change the line which says:
 +
 +  smtp               ​25/​tcp ​   mail
 +
 +so that it says:
 +
 +  smtp               ​5025/​tcp ​ mail
 +
 +Then restart Windows NT.
 +
 +===To set up forwarding of incoming mail from VPOP3 to Exchange Server===
 +If you have a catch-all email account at your ISP:
 +Go to the ''​Local Mail -> LAN Forwarding -> Configuration''​ page in the VPOP3 settings. In this LAN Forwarding configuration box put a line like
 +
 +  *@mydomain.com ​   192.168.1.1:​5025
 +
 +where ''​mydomain.com''​ is your registered domain, or the subdomain given to you by your ISP, and ''​192.168.1.1''​ is the IP address of the Exchange Server computer.
 +
 +Also, in the ''​External Mail -> In Mail''​ page in the VPOP3 settings, make sure that the ''​Extended Email Routing options''​ main radio button is set to ''​Route According to Detected Recipient''​.
 +
 +Alternatively,​ if you have individual email accounts at your ISP, in the ''​External Mail -> In Mail''​ page in the VPOP3 settings for each ''​In Mail''​ setting, set the ''​Extended Email Routing options''​ main radio button to ''​Forward all messages to another LAN mail server using SMTP''​
 +
 +Then, in the configuration boxes put the email address on the Exchange Server, and the IP address:​port of the Exchange Server SMTP service.
 +
 +===To set up forwarding of outgoing mail from Exchange Server to VPOP3===
 +On the Exchange Server ''​Internet Mail Connector''​ Connections tab, in the ''​Message Delivery''​ section, choose ''​Forward all messages to host:''​ and enter the IP address of the VPOP3 computer.
 +
 +===Avoiding other port conflicts===
 +Because both VPOP3 and Exchange Server are mail servers, they may both try to use the same TCP/IP ports which will lead to conflicts if they are both running on the same computer. This happens with port 110 (POP3) and 389 (LDAP). To stop these conflicts, either disable these protocols in the Exchange Server settings, or change the ports assigned to these services in the VPOP3 Local Servers tab.
 +
 +====VPOP3 and Exchange Server on different PCs====
 +To set up forwarding of incoming mail from VPOP3 to Exchange Server
 +Go to the VPOP3 ''​Local Mail''​ tab and press the ''​Edit LAN Forwarding''​ button. In this window put a line like
 +
 +  *@mydomain.com ​   192.168.1.1
 +
 +where ''​mydomain.com''​ is your registered domain, or the subdomain given to you by your ISP, and ''​192.168.1.1''​ is the IP address of the Exchange Server computer.
 +
 +===To set up forwarding of outgoing mail from Exchange Server to VPOP3===
 +On the Exchange Server ''​Internet Mail Connector''​ Connections tab, in the ''​Message Delivery''​ section, choose ''​Forward all messages to host:''​ and enter the IP address of the VPOP3 computer.
