A rather complicated issue...I don't even know if a solution is possible!

I have internet connection at a central location. At a number of other remote locations, I have PCs without internet connectivity. I am looking at a solution by which one or many users at the remote locations can have their email accounts synchronised through the computer at the central location. The data is moved between the central location and the remote locations on a flash memory device or an optical disk.

Could there be a software solution to this issue that has a server-client MODEL? It would be better if the emails could be synchronised in the background under a password protection without the operator at the server end being able to read them.

I am open to windows or Linux solutions.So, you're wanting to get email distributed to computers not connected to the Internet. Seems like an absurd notion to me. If you really need email at those "remove computers", why aren't they connected to the Internet?

Have you considered some other solution such as an email app on smart phones? Or, sending email to cell phone text messages using a service such as http://americas.clickatell.com/solutions/global-sms-gateway/?gclid=CI-29a2RvrgCFaI7MgodCisAfw#.UeqK5kD8iIU ?I agree that it sounds absurd, especially in today's wired world!! But there are places on the planet that still are away from wired and wireless communication, and I am in one of those places.

Putting things into better perspective, the central location that I have mentioned has a satellite internet connection. The remote locations that are several km apart can neither be connected to the internet not to the computer at the central location through any medium.

I am looking for a solution where the persons at the remote locations can have the email addressed to their email ids DELIVERED to the computer at the central location. Several persons will obviously have several different mail addresses. Is it possible for the emails received at the central location to be sent to the remote locations on any removable media and read by the users there? And conversely, the users at the remote location compose their emails, and send them to the central location on removable media, to be transferred through the internet.

Though a person at the central location can open each remote USER's mailbox and save the email on a medium that can be sent to the remote location, it is INTRUSIVE and lacks privacy.

In effect, it calls for a system where I can have a number of mailboxes configured in the central computer, which get synced with corresponding mail boxes on the remote computers through a flash drive or CD.

I can understand that the requirements are strange, and very unconventional! I frankly cannot think of an easy, workable solution - that's the reason I have put it on the forum for the geekier guys to figure something out!Mozilla Thunderbird®, Portable Edition comes to mind as a possible solution; more info @ http://portableapps.com/support/thunderbird_portable. This is an email client that runs on a flash drive. Perhaps you should also assess whether POP or IMAP email would WORK best for your situation. To use IMAP, your ISP will have to support it, so you would need to confirm that before setting up IMAP in your email client. By the way, Google's gmail can be set to work in IMAP mode.
