As an example, here's how it functions with Hotmail and Yahoo; maybe your program works similarly...
Yahoo:
1. Under Folders, enter the name of the folder (e.g., Reply to Post) in the box for "Add Folder," then click on Add Folder.
2. Under Mail Options, click on Filters. There, click on Add Filter. Set the following rules:
From Header: [i]contains[i/] en world
Subject:
contains reply to post
Move the Message to: Reply to Post
Hotmail:
1. Click on View All Folders. Click on Create New, and then do so.

2. Click on Options. Click on Custom Filters.
Set the following rule:
If
Subject contains reply to post
Then deliver to Reply to Post
Hope it helps!
