MaiLScanner doesn't do *anything* with /etc/mail/access.

This message certainly indicates that you have two lines in
/etc/mail/access with key "discountbuyers.info"; makemap doesn't
like duplicate keys in the default ("hash") DB format. Do a `grep -n
discountbuyers.info` on /etc/mail/access to find them.

I've still got a fairly hefty access file; it's full of confirmed,
sturdy, obdurate beggars^Wspammers, and it's worth keeping in place
to reduce the load on sendmail, MailScanner, ClamAV, and SpamAssassin.
Remember, if you reject the session at the initial connection request,
then you don't need to accept the mail and run all those CPU-and-disk-
intensive processes on it.

$ wc -l /etc/mail/access
    5613 /etc/mail/access

Here're my mail stats for the past 8 days, to give you an idea of
what I reject when:
