[HECnet] HECnet-internet mail gateway update.

I've been rewriting the code that does address rewriting for mail that passes between MAIL11 and SMTP the last few days, and I think I got it sorted now. So, if people have tried, and found either funny, or non-working behavior please try now, and see if thinks look better. I've also been testing with VMS MAIL, which uses MAIL11 in some more creative ways, to make sure it gets translated in reasonable ways by my RSX gateway. As a warning, the CC field in VMS MAIL might not be totally correctly handled yet.
