Email hosting

Does anyone have any experincing in quantifying, in terms of dollars, what I should expect to pay for outsourcing an email system. I'm looking at ~1000 mailboxes and am primarily interested in POP3. Any suggestions? Dan Lockwood Office: 530-225-0261 Mobile: 530-949-1302 Pager: 888-578-7218 CompTIA Network+ Certified Microsoft Certified Professional + Internet Cisco Certified Network Associate
