EASendMailObj consists of two objects: IMail and IFastSender. IMail interface provides the basis of sending email. It supports CC, BCC, multiple attachments and ESMTP authentication. It fully supports asynchronous operating mode and event driving. It also provides advanced features such as embedded picture, alternative text, email digital signature and email encryption. IFastSender interface enables your application to send mass email in a threadings-pool with highest performance. Both IMail and IFastSender can send email under SSL/TLS channel.
|
Send email with single thread under synchronous or asynchronous mode. It also provides rich interfaces for email composition. |
|
| FastSender |
Send mass emails with multiple threadings and very high performance. |
Example
[Visual Basic 6.0, C++, JScript, Delphi] The following example demonstrates how to send email with EASendMail SMTP Component, but it doesn't demonstrates the events usage. To get the full samples of EASendMail, please refer to Samples section.
