Hi,
I need to implement a massive mailing solution and I would like to know if zimbra is the ideal solution with either the opensource version or the licensed version. The idea I have in mind is a multiserver installation in HA with 2 MDA and 4 MTA each with a different public ip, but I have doubts about the rolling of the MTA, is it necessary to have some nginx of balancer? or zimbra automatically performs the balancing ?.
I hope you can clarify my doubts and if there is a better scheme to let me know.
Regards.
