The polling MailTo transport supports sending messages (E-Mail) over SMTP and receiving messages over POP3 or IMAP. This transport implementation is available as a module of the WS-Commons Transports project. The receiver and sender classes that should be included in the Carbon configuration to enable the MailTo transport are org.apache.axis2.transport.mail.MailTransportListener and org.apache.axis2.transport.mail.MailTransportSender respectively. The JAR consisting of the transport implementation is named axis2-transport-mail.jar.

The mail transport receiver should be configured at service level. That is each service configuration should explicitly state the mail transport receiver configuration. This is required to enable different services to receive mails over different mail accounts and configurations. However, transport sender is generally configured globally so that all services can share the same transport sender configuration.

Service Level Transport Receiver Parameters

The MailTo transport listener implementation can be configured by setting the parameters as described in the JavaMail API documentation. For IMAP related properties, see IMAP Package Summary. For POP3 properties, see POP3 Package Summary. The MailTo transport listener also supports the following transport parameters in addition to the parameters described in the JavaMail API documentation.
