an unpatched default qmail will accept anything if its in virtual host 
mode, then another of its processes will bounce it, dumb yes, which 
amazes me in its default way bernstein claims its so secure (and look 
theres those lil piggies flying backwards through the air <G>)
so its possible some MTAs like qmail are too dumb to do it any other way 
:)

however the chkusr patch fixes this flaw in 15 seconds.
I'm not aware of any other MTA operating this braindead way.
