To install SCSmail all you do is create a folder for it, copy the downloaded EXE file into it and run the EXE. It will create some empty folders as temporary receptacles for your mail. Next you need to set the program up. This is accomplished by entering the name and login credentials of your POP3 and SMTP servers at your ISP or mail provider. You also provide the details of where to find your TNC (what com port and so on) and can also set up CAT control for setting the transceiver frequency. I used the Kenwood setting which worked fine with the Elecraft K2 to which my TNC is connected.
|SCSmail mail client configuration|
The setup is:
your email client (such as Outlook Express) -> SCSmail client -> SCS TNC -> your radio transceiver ---> the ionosphere ---> server transceiver -> SCS TNC -> SCSmail server ---> the internet -> your ISP mail server
One advantage of SCSmail is that you can use your own familiar email client (such as Outlook Express) instead of an unfamiliar one like RMS Express. You can also use your own email address instead of having to use a special one @winlink.org. But you pay a price in speed for this.
To reconfigure your mail client to use SCSmail you simply change the addresses of the incoming and outgoing mail servers (usually something like mail.yourisp.com) to localhost. You can then send and receive mail just as you would normally. This is obviously an advantage if you are setting up an HF mail system for people who don't want to learn a new way of doing things.
|Receiving mail using SCSmail|
I connected instantly to the server on 20m using 10 watts to my attic dipole. But compared to Winlink's RMS Express SCSmail is slow. This is probably the penalty for using protocols designed for use on the wired internet over a wireless HF link. Winlink and RMS Express are optimised for HF use. RMS Express creates efficient small text mode emails whereas Outlook Express creates messages that can contain lots of fancy formatting and unnecessary header lines which increase the time to send and receive.
It all worked (or mostly did: the test emails I sent myself and Helge still haven't turned up.) If I owned a boat or a log cabin miles from the nearest telecoms provider I might find SCSmail a useful facility to have. Even though I haven't, it was still an interesting thing to try out.
