I think one of my earlier users may have turned to me for help precisely *because* your servers would not relay his mail. :-) At any rate, fair enough, I'll just wait for the bounces to come in, and see how bad the problem really is. I only serve a few users (about 10) and many of them aren't non-English speakers natively which is where the problems really seem to be, with custom software running somewhere in the east.
