The SMTP component provides an easy to use API for communicating
with SMTP servers and sending e-mail. Written using 100% Java and
delivered as a Java Bean makes the SMTP component usable in a wide
variety of IDE and platform configurations. Download

Features
- File attachment support - The SMTP
component provides a simple API for adding one or more attachments
to a e-mail message. Using this API one can easily add one or
more attachments from a file or URL.
- Bulk mail support - For targeted mail campaigns built in
Bcc: (blind carbon copy) support and the ability to define recipients
from the contents of a file provide an easy API for delivering
bulk e-mail
- HTML message support - For e-mail clients capable of rendering
HTML, this feature allows one to send rich-text e-mail to recipients
in the form of a web page.
- E-mail. address validation - The SMTP component supports
all valid e-mail address formats specified in RFC 822. SMTP
and EmailAddress components offer syntax validation of address,
prior to sending e-mail message. This capability reduces network
traffic from bounced e-mail messages and provides a way of systematically
identifying invalid e-mail addresses.
- User authentication - Methods to support username/password
authentication for SMTP servers which require authentication
to prevent unauthorized SMTP relay.
- Message priority support - For e-mail clients which support
message priorities, the SMTP component allows prioritization
of an e-mail message. A message with "highest" priority
would potentially give the message higher visibility in a recipients
mailbox.
- Header management - Easily define SMTP e-mail header values
for submission with a e-mail message. An example might be to
set the X-Mailer header typically used to define the client
software responsible for generating the mail message.
Code Example
The following code example demonstrates how to send an e-mail
along with an attachment using the SMTP component.
