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.

*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 3 and 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"?>
