Setting out-bound SMTP port to a number other than 25

Typically, out-bound emails are sent to port 25, which is the default value for SMTP protocol. Depending upon your network configuration you may want to send out-bound traffic to a different port.

Consider the following scenario

• You are using Xeams in Firewall mode.
• You have configured your primary SMTP server to listen on port 2500.
• Due to some internal network complications you do not want to use the SMTP Proxy Server.
  
• You need to configure SMTP server to listen on port 25 and have it forward in-bound emails to port 2500, which is the SMTP port for your actual email address

Following steps demonstrate how to force the SMTP server to forward emails for certain domains to a port other than 25

• Login to Admin Console as administrator
• Click Manage Local Host File under Server Configuration
• Enter the desired domain name. This is typically the local domain handled by your actual SMTP server.
• Enter the IP address of your actual SMTP server followed by a colon and the port number.

Refer to the following image for an example.



This example will force the SMTP server to send messages for abcd.com to a machine running on 192.168.1.10 on port 2500
