Mail Filtering 100s of addresses?

I'm trying to limit my push e-mails to items from people I know. I'm on BIS, rather than BES. It looks like the usual filter process would make me enter almost every one of a couple hundred addresses. Doing a domain name filter won't help much because most are personal e-mails on very common domains like aol, hotmail, etc. I mainly use a Hotmail address. I used to be able to use a MSN Messenger filter to limit e-mail alerts to people already in my address book. Any way to achieve something similar with BIS filters without spending a weekend typing in each address?

Don't know if this will help. Take a look http://forums.crackberry.com/f3/how-...ackberry-5736/
