Syntax

object.Command Owner, User, Command



The Command Method syntax has these parts:

Part Description
object An expression evaluating to an object of type IwodImapNotify.
Owner Required. A wodImapServer object.
User Required. An ImapUser object. Reference to user that issued command.
Command Required. A String value. String expression that represents command and parameters entered.

Remarks
NOTE: This method is called only if you implemented IwodImapNotify interface in your application, and wodImapServer1.Notification property has received reference to instance of your implementation.
 
This notification method will be called each time user issues some command, no matter what user's state is set to. For instance, after Connecting notification you will not receive any additional notifications until user sends username/password combination. However, if you're interested if he's testing your server for some other commands or vulnerabilities, you can just track down every command he sends using this notification.

You should understand that this notification is called in the middle of the chain between user's command and IMAP server's processor. This means that before IMAP server receives this command and evaluate it, you will receive this notification where *you can change Command parameter*. Changing this parameter will directly affect IMAP server's behaviour. For instance, if user sends command 'LOGIN test test' you can do
 
Command = "LOGIN joe joe"
 
Do you have idea what will happen? IMAP server will receive (false!) username/password combination as you changed it, so it will try to login user joe/joe instead of test/test. Later you can change any particular command like this.

If you don't like how IMAP server reacts on specific command, you can change that too. Just use Send method to send custom data, and set Command argument to empty string - and wodImapServer will ignore this command (you already sent response, didn't you?) But - try to read IMAP specifications before you do anything like that.


More, if you want to implement new command, for instance 'HELP' command you should do: test if command is entered, set Command parameter to empty string, and Send some response manually using IMAP protocol specification.
