I have a pop account and use it like you are describing.
In versamail you need to set under options, preferences, server, leave a copy on the server. This allows you to check your mail and when you get home you can retrieve it from your pc.
This might help the other part of your problem or maybe not. In versamail go to options, preferences, delivery and select get only mail 1 day or three days etc.. If you check your mail over and over you will keep getting it but only 1 days worth if you select it.
