Yes, Using /etc/tcp.smtp you can set the env variable for inbound,offnetwork connections to check MX records I have :allow,DENYMAIL="DNSCHECK",SANITYCHECK="TRUE",RETURNMXCHECK="TRUE",SMTP550DISCONNECT="TRUE",BLOCKRELAYPROBE="TRUE" DENYMAIL is old and not used anymore, Depending on your version of qmail-ldap it may work. RETURNMXCHECK is the env variable you are looking for. check out QLDAPINSTALL docs for the definition of the others. > A simple way to reduce spam is to check if the incomming e-mail has a > valid MX record.
