General information

wodSmtp is a Client ActiveX Component that is used to deliver email messages directly to the server of the recipient, using SMTP protocol. It automatically finds appropriate server where message should be delivered, or uses SmartHost through Hostname property.

It includes several one-line methods for sending entire email (including attachments). It can also load prepared messages (created with Outlook, Outlook Express or any other client), reformat it, change its properties, and send automatically.


Using wodSmtp you can easily get create new message and send it to destination SMTP server. wodSmtp will try all mail-exchanger hosts defined for the recipient, and will try to deliver as long as message isn't successfully delivered. If delivery fails (for whatever reason), you will be notified about it through events.

Messages can be sent just by using one line of code, with methods that are self-explanatory, such as:

Smtp1.SendTextHtmlAttachment "john@doe.com", "general@weonlydo.com", "This is a test", "Hi there!", "<HTML>Hi There!</HTML>", "c:\myattachment.zip"

but it can also be built from scratch by adding only elements you need - through From, To, Subject and additional properties that will inject information exactly where it should be in the message.

wodSmtp also have strong support for message creation and parsing - you will be able to access every aspect of the message directly from wodSmtp - without requirements for 3rd party libraries. This includes direct access to HTML and Plaintext parts, From and To fields, Subject etc..
