sendmail has to either be the final recipient or a relay for it.

correct

I was hoping he'd pipe up. He and I worked on some milter issues before. I use 
it on the linux-sxs.org site, but it's not this damn complicated.

right. mgmt isn't gonna buy it

true dat. but that's they way it currently is... which is why my proposed 
solution is such a hot item
