| NORELAY | ; We want to prevent this site from unwittingly acting as a relay
; domain for spammers or viruses. Such nefarious ne'erdowells ; typically route their mail through unsuspecting sites to "launder" ; it. The unsuspecting sites forward it onward. ; XMC("HELO RECV") contains the sending site's name. If we ; were to be truly vigorous about this, we would find out the IP ; address of the site and do a reverse DNS lookup to verify the site's ; name. We don't yet have that capability, so we'll have to make do ; with XMC("HELO RECV") and trust that the site is who it says it is. |
