Hello Postfix Probably not the first one with this question, but please i need a little help!
If sending any Mail to GMX or WEB.de, i have here this error, Please view Mail.log last two lines. i undestond that GMX will check the Resolver-Name, "dynamic IP Ranges" Yes true i'am running now with dynamic IP Address "DSL Connection" but also running a service like No-Ip that will forrward the MXrecord, mail.caloro.ch. But exist here any way to solv this issue, or are here the only way to buy Static-IP Address so GMX can Resolv the Name from Sender correct? or i have understond any thing wrong here? Best regards for any Help!!

These lists contain dynamic IP addresses and IP addresses currently known to be spam senders. Please contact your system administrator and/or email provider who should check if the IP address they use is on one of these RBL (Realtime Blackhole List) and who should then take the necessary steps to have the IP removed. In addition to this, we manage our own Black lists based on various criteria.
