Re: Bluewin Error: Der MX-Eintrag fuer die Domaene aerni.com kann nicht verifiziert werden

Hi Benoit,

Maybe Bluewin requires a matching PTR? Currently 87.102.181.130 resolves to cable-static-181-130.breitband.ch <http://cable-static-181-130.breitband.ch/> and not to mail.aerni.com <http://mail.aerni.com/>.
