Is there any program/script that will check many pop mail accounts?

With forwarding becoming harder and harder to find, I'm wondering if there is any solution out there to take a large list of email account logins and "pop" them for messages, then forward or download new mail?

Seems the usual bat, outlook, etc. have some limitations on accounts and it's rather tough to get large numbers of accounts loaded in them easily as from a csv file. Thanks for any ideas, and yes I'm willing to pay or buy a product out there if it exists.

I used once something similar but with a domain. Search google with: import multiple email pop accounts and check out the first result. Good luck
