Tony,

  Yes, it does. The primary MX points here and the A record points to our
static IP address.

  Long ago, I inadvertently was sending outbound mail through our ISP. When
I learned of this I fixed it so sendmail went directly out. Now, postfix
does, too. I've not yet set up our own DNS server, but that's on my list of
things to do.

  It's got something to do with the sequence of spam checks in main.cf. When
I comment out header_ and body_checks, the mail goes out. When I don't
comment them out, it bounces. Ergo, it should be fixable. But, I don't know
how to fix it.

Thanks,

Rich
