We've been talking about the new LEMONADE standard for mobile messaging for some time and how we have plans to incorporate it into our IMAP/POP server (M-Box) and our SMTP Server (M-Switch).
As of yesterday LEMONADE moved out of the 'intend to do' category and moved into the 'have done' category when Isode sent the first message, outside of a test environment, that demonstrated a key LEMONADE function, the ability to forward a message to another recipient without first downloading it - a key capability for mobile devices like PDAs and Mobile Phones with limited storage and bandwidth.
We forwarded without downloading, over a GPRS link, two messages to Josh Maher and David Ferris of Ferris Research in preparation for a webinar that we're participating in this evening (more details and signup link).
The first contained PowerPoint presentations and PDF documents from a Ferris webinar that took place a month or so ago. The forwarded message was 55Mbytes in size but using forward without download only 2.2 kBytes of data were sent and 1.53 kBytes of data received by the client during the operation.
That's 15,099 times more efficient than forward with download.
The whole process took 26.3 seconds compared with the four hours plus it would have taken had you been insane enough to try this using normal forward with download over a GPRS link.
Because one of the recipients uses a Gmail address (with a 20Mbyte message size limit) we then sent a second message with a single attachment, one of the group of attachments forwarded in the first message. This demonstrated the LEMONADE capability to access parts of messages that have not been downloaded.
Forwarding that message without downloading was 'only' 1739 times more efficient than forward with download and took 7 seconds.
We believe that this is an important step - bringing LEMONADE out of the lab and into the real world.
