i did the postmap hash:/etc/postfix/relay_check
i can't see what i'm doing wrong.
i have been reading the web pages people are sending me to, but
if the answer is there i can't figure it out. i haven't tried
the regexp N. Jones suggested. that'll be harder to try because
there's an automatic updating process that will change things behind
my back. i'm still thinking about how to do that.
