[REBOL] How to Resume sending email?

[carloslorenz]

Rebols,

Let's say I have this

    files: [%../tvprog/cnn.txt %../tvprog/car.txt %../tvprog/tc1.txt]

    foreach file files [send [EMAIL PROTECTED] read file]

    quit

And suddenly the connection is lost. How can I resume the process and be
sure it will not resend some messages?

Thank you all

Carlos
