Accepting messages from a domain lacking MX records might be risky due to the high rate of domain turnovers. Within a few weeks, more than the number of existing domains will have been added and deleted by then. Spammers take advantage of this flux. Unfortunately SMTP server discovery via A records is permitted and should be deprecated.
Should be (perhaps) but clearly isn't. When you run it through a standards body and/or obtain broad acceptance; great! Until then, it's pipe dreaming.
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.
