I would like to use SmarterMail mail server exposed to the Internet to receive mail for my customer who have "in house" an exchange server, and do not want to expose this to internet.
SmarterMail free configured as Incoming Gateway with mode "domain forward" should be right for this, right ?
I must then specify which domain to forward to the server end (in my case the domain on the Exchange server to the customer) ?
If I want to have a second SmarterMail server, as a matter of high avaibility, this second server I configure it as a backup mx or even as this incoming gateway mode domain forward?
