AW: weird MX behavior

[Grundner Wilhelm]

hi mark,
hi kevin,

thanks for your help and your explanation.
i really didn't notice how basically wrong my config was ...

additional info :

it got a mx record for "mydomain.com" with the wrong config
(via dig), but not for "funny.mydomain.com" ...

thanks again!

best regards
Willi Grundner

>   also insures that a cached CNAME can be used without checking
