What proportion of valid mail in NZ is sent from an address that doesn't have an MX record? Do you check? What do you do if it's not? If one were to block email from addresses without MX records, how much would break? How many complaints would one get?

You'd break a bit. Lots of automated emails come from addresses like "root(a)machine.domain.co.nz" which won't have a MX record or possible any (remotely viewable) DNS at all. Unless you are going to block a huge amount of spam by doing it then it is probably not a good idea. -- Simon Lyall | Very Busy | Web: http://www.darkmere.gen.nz/ "To stay awake all night adds a day to your life" - Stilgar | eMT.
