You have multiple options 1. Ironport / Fortinet etc gateways. [Not barracuda - hardly carrier class, enterprise grade more like it]
2. Outsource to a provider like Messagelabs or MXLogic that only handles the spam filtering, lets you host your own mailboxes 3. Outsource to one or more vendors of hosted email services - Google Apps, Microsoft BPOS, IBM Lotuslive etc your choice based on what meets your requirements. --srs (full disclosure - head, antispam @ ibm lotuslive) 2010/4/12 Alex Kamiru <nderitua...@gmail.com>: > I am in the process of sourcing for a carrier class email security > solution that will replace our current edge spam gateways based on open > source solutions.
