AllowExtensions Property

A switch allowing the component to use ESMTP features (SMTP extensions).

Syntax

 smtp.getAllowExtensions([callback])
 smtp.setAllowExtensions( allowExtensions, [callback])

Default Value

TRUE

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getAllowExtensions([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setAllowExtensions([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property is a switch allowing the class to use ESMTP features (SMTP extensions). If this property is true, the class will first send the EHLO greeting to the server and, if that fails, the standard HELO command will be sent.

This property is true by default but may be disabled if it's known in advance that the MailServer doesn't support SMTP extensions.

This property is not available at design time.

Data Type

Boolean
