Hello Howard,

1) Check /etc/mail/sendmail.cf and look for line that looks similar
or identical to this:

Kaccess hash -T<TMPF> /etc/mail/access

If it is enabled, one can conclude the following:

        a) Access list uses HASH database;
        b) Access list in in /etc/mail/access file;

2) So, edit /etc/mail/access (or as I often rename it:
/etc/mail/access.txt) and add:

192.168.33.66 OK

If you not only want to allow this unresolvable IP address to
send email to your domain, but relay through you too (to send
messages to other domains THROUGH your gateway):

192.168.33.66 RELAY

3) Rebuild the hashed database:

cd /etc/mail
makemap hash access <access.txt

That is all. Stay happy and be at peace with computers and people.
