Why do you want to have a master-slave ? Hire services of a Mail Server (dedicated or shared .. depending on your budget ) wherever bandwidth/reliability is good. May even be in a different country All the Anti-spam / anti-virus happens on the Remote server and from there pull all mails to a local server using uucp ( yes it still works excellent ) whenever you have power and bandwidth Route the outgoing mails too the same way This is the same idea used by many places over here too. Power many not be the issue, but reliable bandwidth is still a real challenge in rural places Thanks Ram
