As a developer, if you've ever tried to interface with desktop email clients from your own applications you would probably agree that at best it's a pain. Outlook, Outlook Express, Thunderbird and Eudora have totally different APIs, so it means a lot of code rewrite each time to interface with each of them.

If you've taken a look at our Mailbox-SDK you'll already know that we've simplified the task of doing all this communication, providing just one API so you can pick your email client and let us do the hard work. Well we've just released the latest version of the Mailbox-SDK which has a couple great new features which now come included.

First up is our EMLtoMSG and MSGtoEML email converter API. This lets you convert between the .EML and .MSG email message formats used by different email clients. We've even supplied a drag and drop demo application, written in Delphi, that demonstrates this ability. You can drag and drop an email from Outlook Express and the application saves it to disk in the Outlook format, really handy for making email aware applications, converters and more.

Next is our new Mailbox Restore API. As you may know Outlook and the other email clients save emails as part of a single mailbox file. It's all very well being able to pull out files from a mailbox and save them to disk, which the Mailbox-SDK already does, but what if you want to restore those emails back into a mailbox? Well that's what the restore API is for; perfect for writing email archiving and backup applications.

If you've taken a look at our Email Extractor application you'll know that it was written on top of the Mailbox-SDK, and uses it to extract, backup and restore emails from any email client. As we've been selling the Mailbox-SDK for some time now we thought it would be a great idea to also offer the source code for the Email Extractor as one of the purchasing options. The Mailbox-SDK already comes with demo apps, but if you want a fully fledged example you may want to buy the Email Extractor Source too.
