[spambayes-dev] forwarding and replying to emails

[Jeff Epler]

The error message
    553 sorry, that domain isn't in my list of allowed rcpthosts
is not from spambayes.  It comes from some other piece of software.  If
it happens when you send to anyone outside your office, then the problem
is probably in the configuration of your organization's mailserver.

You should contact the person who is in charge of your organization's
mailserver, including the same information as your previous message.
