My fault. You are right. There is no good reason to try a second MX if I=

get a 5xx error.

There still remains the 4xx error situation and the "Connection timed

Yes you are right again. I mentioned this because I had this problem
with a very old Courier version I was running some time ago. Old problem=

already solved.

But again ther still remains the server too busy situation where I end
getting a "Connection time out". Wouldn't it be good to try a second MX
here?
