No. I don't mind, but the resulting access file is about 1650 lines long
and would be of no interest to anyone who does not run sendmail.  If you
desire then I will send it to you as an attachment.

the access.db does not handle CIDRs so one has to convert the DROP list to
all of the included B or C netblocks. For example something like
A.B.64.0/21
would result in access entries:

# A.B.64.0/21 - Spamhaus DROP entry
A.B.64     REJECT
A.B.65     REJECT
A.B.66     REJECT
A.B.67     REJECT
A.B.68     REJECT
A.B.69     REJECT
A.B.70     REJECT
A.B.71     REJECT
