[I don't think there's a Mail API in Java 1.1,
but there may well be one in 1.2, so this
applies if you can't wait for 1.2 to be
shipped for Linux.]
The best way is probably to allow an external
program to be configured which will actually
send the mail.
Have a configuration string, initially set to:
``/usr/lib/sendmail -t''. Allow people to
reconfigure this easily.
To send mail, start this program and pipe the
mail message to it, including To:, Cc:, From:,
Subject: and all other headers as required.
Make sure there's a blank line between headers
and message, and finish the message by writing
a single ``.'' on a line on its own. You may
need to escape ``.'' characters which appear
as legitimate parts of the message at the
beginning of a line.
For portability to Windows, you will unfortunately
have to write a little program which replaces
sendmail. It just needs to accept the message
and connect to a *user-configurable* machine
and SMTP port. (Note that most mail can be
relayed locally - it does not need to be sent
directly to the final mail server).
