Hi,
I'm reviewing an ironport architecture, and especially an incoming relay (ESA C370, AsyncOS 8.0.1). I have two domains, hosting by two different mail servers. The relay only accept mails from Internet and can only send to the two mail servers.
The current configuration is two public listeners, one for each domain. As incoming policies apply to both, I am asking myself if I really need two listeners.
What is your opinion about advantages and inconvenients having two listeners instead of one ?
Thank you for your help
Best Regards
Quentin
