General

This page allows you to rename the server, define the address and port the server will be bound to, set the timeout for the service and enable logging of connection to this service.

The default port for POP3 connections is port 110. The server should only be bound to an address for additional security. In most cases it can be defined as 'Any unbound address'.

Property	Description
Address	This is the IP Address which this service is bound to. This should, in most cases, be left set as the default of "Any unbound address" in the drop-down list. Selecting an IP number here will bind this service to that IP number, and only allow connections on that number. If you choose to bind the server to an IP address, select the IP address from those available in the drop-down list.
Port	Defines the port this SMTP server will use for incoming connections. Port 25 is the default SMTP port. By convention all applications, servers and services using SMTP to communicate use this port.
SMTP idle timeout	Defines how long the SMTP server will remain connected to a host or client with no activity before disconnecting.
Custom SMTP Welcome Text	This text is used as the text in the welcome response when something connects to the server. If this is left blank then the default text is used.
Reject Messages that have had more than 'x' hops.	Defines how many "server to server" hops a message can have before being rejected. This is used to help prevent mail being passed around from server to server forever in a loop.
Reject messages that are larger than...	Defines the maximum size of message this SMTP server will accept. This is a global setting for anyone using this server, with all connections to it being affected.
Add all SMTP output to log	Writes all activity to the log, in the location defined on the Log properties page. Note: ALL data will be written to the log (including the message content) if this option is selected/enabled. This option should only be used to help diagnose problems.
