I've noticed some spam sending hosts, which use e.g. localhost/ 127.0.0.1

there a settings to get rid of that?


Better would be a patch to qmail-smtpd that only accepted localhost and 127.0.0.1 as the HELO name on connections from 127.0.0.1. I don't know enough about chkuser to answer your original question.
