*nod* The "and friends" part I was referring to, worth extending your internal network for. Those web-forms only send mail to the service's owner, I hope. > If the client can't choose the message text it's at least a bit safe. That would be to third-parties. Regardless how hard abuse of that service would be, proper mail environment is crucial. Which includes the hostname. -- 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; }}}
