It does, but it does give up on the mxbw one.
Your MX-Test or Postfix?
It also doesn't leave a good impression on customers I guess that the ISP can't even have a proper email setup.
thanks for letting me know that i am a moron. ;-)
Nevertheless, I would gently try and suggest to fix it for real instead of letting it run like this.
I wouldn't mind removing GSLB/mxbw (= ditch ns.bwlbmsg) but first i'd like to understand why Postfix doesn't switch to mxzhb/mxzhh.
...Just had a look at the postfix 2.4.6 source (smtp_addr.c) and i don't see why postfix would fail in such a situation.
Could you send me (offlist.. it's getting off-topic) the error message from your maillog?
