I think you cannot match on the "From:" in the mail header.
Remember config syntax and structure in 6.4 will be different from 6.3,
you did not tell what you use...
What I *would* try for -current:
table denydomains { "*.bid", "*.data" }
match mail-from <denydomains> reject
match helo <denydomains> reject
"smtpd -n -v -f" says that's OK, I'm not going to test it live.
And it's only for "MAIL FROM:" and "HELO", easy to forge.
I think with 6.3 (or earlier) this is *not* going to work, unless
someone sends with "MAIL FROM:<me@biz>":
table badsenders { "@biz", "@date" }
reject from any sender <badsenders>
