Nice pointers. I guess. ;) I don't manage any Windows servers, and I frankly don't want to. So can't help here myself. What I can do, however, is to split up the original question into manageable chunks, as unrelated as possible. SA and postfix on Debian? Check. Postfix talking to a backend Exchange server... Identified problem, waiting for others to step up. Like you. :) -- 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; }}}
