Can I have an external SMTP server to be used with AC7.5SP1?

Hi,

I have an edge and 2 clustered Origin servers external to the organization. (Edge is used as reverse proxy).

Can we use our organization SMTP server with this set up? Or should SMTP server reside in the same network as the set up?

If yes, which IP addresses do I need to open Port 25 for on SMTP Server? Edge, Origins, Load Balancer or all three?

Please advise.

Rgds,
Rahul

You can use an external SMTP server. Your origins both have to be able to communicate out on port 25.

My Origin Servers have a Public Facing IP address. Do you think if I get port 25 opened for these 2 IPs at the organizations firewall, the SMTP server can recognize the Origin servers residing outside on a different data center?
