*Sending mails* {center}

* Step 1: A JBI Consumer sends a Message Exchange to the Mail Binding Component.
* Step 2: Mail Binding Component processes the Message Exchange: transforms it into a mail message and retrieve targeted External Provider Service (email address) linked to the endpoint set in the Message Exchange.
* Step 3: Mail Binding Component sends this new mail to the targeted External Provider Service (Business Service, simple email account...).

h2. Dynamic Exposition

The component can expose directly a generic SendMail service without deploying a service unit.

To allow the component to provide his generic service, the component must have a wsdl with the name: component.wsdl. An example of this file is present in the component.To deactivate the generic service supplies by the component,simply erase the file: component.wsdl.

This service offer two mode:

* In-Payload mode: The service allows the consumer to send a specific XML message to the component, which defines all the information needed to send an email.

The IN message looks like :

{code:lang=xml}
<ns0:mail xmlns:ns0="http://petals.ow2.org/components/mail/version-3.0">
         <ns0:host>localhost</ns0:host>
         <ns0:port>25</ns0:port>
         <ns0:user>user</ns0:user>
         <ns0:password>pwd</ns0:password>
         <ns0:scheme>smtp</ns0:scheme>
         <ns0:from>from@from.com</ns0:from>
         <ns0:reply>reply@reply.com</ns0:reply>
         <ns0:to>to@to.com</ns0:to>
         <ns0:subject>subject</ns0:subject>
         <ns0:helohost>helo</ns0:helohost>
         <ns0:send-mode>content-and-attachments</ns0:send-mode>
         <ns0:content-type>text/plain</ns0:content-type>
         <ns0:body>My email content</ns0:body>
</ns0:mail>
{code}

* Out-Payload mode: The service allows the consumer to send a JBI message to the component by setting ws-addressing properties in the incoming message exchange which defines all the information needed to send an email.The content of the mail (body) is in the payload of the mesage.

The IN message looks like:
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<mail><body>My Mail Content</body></mail>
{code}

h2. Static exposition

Petals Mail binding component can be configured by deploying a new service unit to it. The jbi descriptor ( jbi.xml file) of this service unit must contain a provides node describing the link between an internal jbi endpoint and an external email address.

Once a provides node is configured, you can start to send email via the mail binding component. You just have to send message exchange to endpoints activated by service unit deployments (containing jbi.xml with provides node).

The IN message looks like:

{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>
<mail><body>My Mail Content</body></mail>
{code}

*Receiving mails*
{center}

Petals Mail binding component (MailBC) allows to receive mails from external consumer and to bind them to message exchanges intinded to internal jbi components. To receive new mails, MailBC can be linked to specific mail stores. It will check these stores periodicaly to retrieve new mails. If it finds a new mail in a store, it will process it (map this mail to a message exchange) and send it to the targeted jbi endpoint. Then the mail is removed from the store. So, all mails (read or unread) in a store are considered as new mail.

* Step 1: An External Consumer Entity (Business Service or simple mail client) sends an email to the registered Mail Store (a classical email account).
* Step 2: Mail Binding Component periodicaly checks for new mails and imports them.
* Step 3and 4 : Mail Binding Component processes this new mails : transforms them into Message Exchanges, sends them to targeted jbi components (step 4) and finally delete them from the mail Store.

h3. Service Unit descriptor

Petals Mail binding component can be configured by deploying a new service unit to it. The jbi descriptor (jbi.xml file) of this service unit must contains a consumes node describing the link between an external mail store and an internal jbi endpoint. Here is an exemple of jbi descriptor activating a new "consumed service" :
{code:lang=xml}
<?xml version="1.0" encoding="UTF-8"?>

<jbi:jbi version="1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
