SMTPS Component [IP*Works! SSL V8]

Properties Methods Events Configuration Settings

The SMTPS component is used to send Internet mail using the SMTP protocol (the Internet mail standard).

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

The SMTPS component is the SSL-enabled equivalent (RFC 2487) of the IP*Works! SMTP component. The main difference is the introduction of a set of new configuration settings, properties and events that deal with SSL security. The SSLProvider configuration setting chooses a security provider subsystem. The SSLEnabledProtocols and SSLCipherStrength configuration settings determine which protocols are enabled and at what security level. The property is used to select a client certificate if the server is requesting client authentication. The SSLSecurityFlags configuration setting, together with the event allow you to check the server identity and other security attributes. Finally, the event provides information about the SSL handshake.

The SMTPS component implements a standard SMTP client as specified in RFC 821. It has a simple plug-and-play interface. It contains a number of properties like , , , , , etc. that map directly to the internet mail message headers with the same name (RFC 822). The message text is set in and/or . Messages are sent by calling the method.

The component supports message delivery to multiple recipients through the , , and properties. Simply specify the destination email addresses separated by commas.

The interface of the component is open-ended. New features, including MIME attachments can be supported by using the property.

A number of events provide feedback during the operation of the component. The event is fired during message delivery to show the number of bytes delivered. The event traces the commands that are sent to the server and the respective replies.
