Re: question about return code .255

Hello Patrick,

Thanks for the reply.

I really should have said local-unbound - the FreeBSD built-in version.

I also see the same return on a friend's postfix server to about 50% of 
queries.  No problem with zen on his server either.

I get your point about not being very useful in postscreen.  

Cheers,
Phil
