Are you sure?  Because if that's the case, there's no reason for the 
second parameter in the return value for filter_relay.

I'll have to look for samples of filter_relay rejections, but I know our 
Sendmail-level DNSBL rejections successfully attach a message to the 
reject code.

I know this because occasionally someone will forward the error, 
complete with "550 5.7.1 No mail accepted from known spam hosts or virus 
sources -- see <URL to look up cause>."  They don't seem to *read* it 
very often, and Outlook/Exchange have an annoying tendency to sanitize 
out the useful error with a generic one, but I do know it at least makes 
it out the door.
