Don't think you're hijacking the thread -- you just stated exactly, what I mentioned in my previous post. The only real problem, validating recipients at the front MX, based on the data in the backend Exchange servers. Everything else is not a problem, even though managing a Linux server might seem to be one from the point of view of a Windows admin... ;) -- char *t="\10pse\0r\0dtu...@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i<l;i++){ i%8? c<<=1: (c=*++x); c&128 && (s+=h); if (!(h>>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
