Messaging
Functional Description

The Messages application provides the user interface to messaging in Qt Extended. It provides the facility to receive emails from multiple mail servers as well as SMS and MMS messages from other mobile phone devices. It also allows email, MMS and SMS messages to be sent to multiple people with or without attachments. SMS messages are sent and received via the GSM cellular network.  MMS and email are sent and received via TCP/IP based networks, usually GPRS on a mobile phone. MMS messages are sent and received over the standard HTTP protocol. Most messages conforming to RFC2822 and RFC2045-RFC2049 are supported as are POP and IMAP authentication. Application requirements include available messaging storage on the device of approximately 1.5 times the server mailbox size and the services of an image viewer are required for viewing image attachments.
