Jul 12, 2009 These proxies cannot interprete or forward SMTP requests. Hence, if your SQL Server is not connected to the Internet (using an Internet IP Address), DBMail does not work. If you want to remain behind a proxy and still want to be able to send emails using GMail or Live Mail, you will need to have, what is called an SMTP Proxy. This tutorial describes the installation of an ISPConfig 3 multiserver setup with dedicated web, email, database and two DNS servers all managed trough a single ISPConfig 3 control panel. The setup described below uses five servers and can be extended easily to to a higher number of servers by just adding more servers.
The following guide describes the steps to add DNS records that route emails from a domain managed in ISPConfig 3 to google apps / gmail. The guide assumes that you have already setup the dns zone for your domain in ispconfig.Login to ISPConfig, click on the DNS module icon in the upper navigation bar, then open the settings of the DNS zone that you want to redirect to google and click on the 'records' tab. You should see a record list similar to this:Now Delete the existing MX record and the 'mail' A-Record.

Then add the following new records:CNAME Record:Hostname: mailTarget: ghs.google.com.MX Records:example.com. 50IMPORTANT: All full domain names like 'ghs.google.com.' Have to end with a dot, if the dot is missing, the name is treated as subdomain of the zone.The resulting record list should look like this.
