But the common thread to this is that every domain that vanishes (and causes email to bounce) has got a bogus MNAME entry (i.e. MNAME is unroutable). This isn't a root specific problem as legacy root users have reported this problem alongside ORSC users. The bogus MNAME may be a red herring, but it's what we're looking at as a possible common cause.On Fri, Apr 19, 2002 at 06:32:58PM -0700, Simon Higgs wrote: > > SOAs with bogus.domain.names pointing to 127.0.0.1 appear to be causing > email to bounce (amongst other things). Ermm... Do you have any actual evidence for this assertion? Yes, but given that all software is broken by nature, and that there is a filing cabinet full of CERT advisories, why would you be surprised at either SendMail or BIND being the culprit under certain circumstances? Maybe even for a totally different reason.An mta that examines MNAME is horribly, horribly broken. I can't imagine anything but the worst sort of spamware actually doing this.
