Answer
The process of running GMS Webmail on the same server as your main mail server is slightly different to running it on a separate server. In this instance you need to ensure that the SMTP service runs on a different port to that of your main mail server. The port the SMTP service runs on can be changed from Incoming > Ports page of the Configuration GUI.
You may for example, elect to run both Sending and Receiving SMTP on port 1025.
You will also need to ensure that the GMS Webmail POST service knows which port its own SMTP service is running on and also where to find the SMTP service of your main mail server. Both of these can be configured under Outgoing > Rules in the Configuration GUI. Assuming that you have elected to run the GMS Webmail SMTP service on port 1025 then your rules might look something like:
* mail.mydomain.com 25 12 glwebmail.mydomain.com glwebmail.mydomain.com 1025 12
From the Users > Add page, add accounts for each user that you want to have access to GMS Webmail. Each of your users once logged on would enter the details of their pop account on the main server under the Server tab. They should specify the name for this profile, the address of the pop server and the name and password of their pop account on the main server. Once this is set they can also specify an interval in minutes that the pop account will be checked at.
Users can if they wish, specify multiple pop accounts and these can be on any pop server, a useful method of amalgamating a number of disperse accounts into the one place.
