No. According to Murphy an A-RR'ed address will be unreachable when you need it most. Then how am I going to tell that you'll have a fair chance reaching the contact at another RR'd address? Apart from that, I don't want to change the contact information when I move to another "primary" mailhost for a given domain. And why should I? We have MX RR's, don't we? Piet
