Okay I wasn't reading this thread but the last few posts have gone a little over the edge. I don't know where this whole "Must have MX record to send email" thing came from but I would have thought domains that don't want to send email can easily mark this fact with a simple SPF record: v=spf1 -all Trying to overload the MX record is pointless when there is a simple method that the domain owners, registrars can choose to use or not. -- Simon Lyall | Very Busy | Web: http://www.darkmere.gen.nz/ "To stay awake all night adds a day to your life" - Stilgar | eMT.
