Remarks

NOTE: This method is called only if you implemented IwodSmtpNotify interface in your application, and wodSmtpServer1.Notification property has received reference to instance of your implementation.

At the time this notification method is called, no commands are entered by user. Only his Hostname and TimeConnected properties are known to Smtp server. Server will call this notification method so you can decide if you will let user access your server at all.

This is very handy if you want to perform IP filter checking on your server, thus allowing only specific range of IP addresses to access server. After you check user's Hostname property, set Action = Allow to let him continue using the server, or Action = Deny to close connection without any response made by your server. You can prevent potential hackers or attackers this way.
