Configuration Settings
The SMTP 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 SMTP 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 SendTo, Subject, From, Cc, BCc, etc. that
map directly to the internet mail message headers with the same name (RFC 822).
The message text is set in MessageText. Messages
are sent by calling the Send method.
The component supports message delivery to multiple recipients through the
SendTo, Cc, and BCc 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 OtherHeaders property.
A number of events provide feedback during the operation of the
component. The Transfer event is fired during message delivery to show
the number of bytes delivered. The PITrail event traces the commands
that are sent to the server and the respective replies.
