Configuring exchange \ Server for backup smtp server
Posted on 2008-10-03
We have an sbs 2003 server here with exchange running our email for our domain,
We have 2 internet connections as the service is unreliable,both have seperate static ip's and are from different providers.
I have an mx record created for connection 1 (mail.company.com) and this is used to receive all our email,
This connection is connected to a firewall which is used then as the gateway on the server so we can receive our emails.
Our hosting company has created an MX record for Connection 2 as mail1.company.com
They have also setup a backup smtp service so that when mail.company.com is unavailable,the backup smtp server will collect all mail and forward it to mail1.company.com (Connection 2)
Is it possible to configure the server to collect mail from both gateways ??
This way,if Connection1 (mail.company.com) goes down,then mail will be forwarded through to Connection2 (mail1.company.com) and will be delivered to exchange automatically without having to change gateways or anything on the server every time it happens
