Default [courier-users] Selectively allowing illegal domains?

I'm using the BOFHCHECKDNS="1" setting in the esmptd configuration file
to automatically reject email from domains that cannot be verified by
DNS.

However, is there a way to configure courier to automatically reject
mail from most illegal domains, but to allow it to come through from
a small, preconfigured set of non-existent domains?

I want to send mail to my personal address from servers at work that
are behind their firewall. All outgoing email from those servers gets
an internal, work-specific domain name appended to the address, and that
name is not known to the outside world. Therefore, the mail is rejected
by my my courier server where my personal address lives.

The probability that I can get the IT people at work to change their
mail software to accomodate my desires is pretty much zip. Therefore,
I'd like to be able to tell courier that this small handful of
internally known domain names from work be treated as being legal, even
though the DNS test fails for them in the "outside world" ... and that
all other mail from illegal domains still gets rejected.

Is this possible? If so, how do I make it happen?

Thanks in advance.
