We're currently using SMS SMTP 5.01, part of our Endpoint Security Mult-Tier Protection. I saw from a couple posts that if we decided to go to the next release (Brightmaal Gateway), I would need to BUY a copy of VMWare ESX 3.x in order to run Brightmail Gateway. Or BUY an appiance version. Is that correct?
What is my other alternative for my smtp gateway if I do not want to go the VMWare route or appliance router? After paying to the yearly maintenance cost, I need to spend additional $$ for the requirement to be able to use the next release. It would be pretty hard to justify this.
Can someone clarify this?
Thank you.
