Two public listeners for two destination domains : usefull or useless ?

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

You don't have to have 2

You don't have to have 2 listeners if the lisenter config can be the same.

Can you use the same IP and MX record for the domains?

Do use seperate certs for the TLS config?  Do you need seperate accept queries (eg seperate AD's)?

If different domains need different IPs (a listener can only be on one Interface), or configs you'll need seperate listeners.
