Yup, a normal round-robin setup on a DNS server will also rotate the list of ip-numbers presented to the "client". Most clients will try the first ip-number given and if that fails try the second etc. As MX records probably don't get the "normal" round-robin treatment it is allways the first listed ip-number which is presented first in the list to the client, and which thereby gets used most often. I might be wrong but I think that's the reason fo the observed behaviour. Groetjes, Bonno Bloksma .... Back up my hard drive?
