and gmx.de


Hello all,

do any of you who do not live in Germany have this error message from 
GMX and WEB.DE? Or is this an educational measure for German providers 
only?


451-Requested action aborted\n451-Reject due to policy 
restrictions.\n451 For explanation visit https://postmaster.gmx.net/de/

https://postmaster.gmx.net/en/case?c=r0103

Hundreds of domains go through our servers, should we now explain to 
every customer that if they, as German citizens, want to send an 
e-mail to other German citizens, especially if they live with Web or 
GMX.de, they must first populate their domains with DKIM entries? Cool 
thing, especially so close to Christmas.


Kind regards
Andreas

We did that too, but after about 200 mails the IP was burned too

Hello,

We have also detected this anomaly on some of our IPs. At the moment 
we have solved it by relaing the queued messages from our other IPs 
and they have been accepted regularly. This is why I thought the 
problem was only ours.


Ciao

Hello all,

since a few hours we have problems with sending to Microsoft. We get 
hundreds of messages like in the subject with the reference to 
S77719. Also colleagues from other companies in germany are seeing 
the same in their logs. All mails that are blocked here are from 
Microsoft customers, but they are redirected through our servers.


Trying to unblock the IP e.g. via https://sender.office.com/ shows 
that the IPs are not blocked.


Anybody have any idea?

Thanks a lot
Andreas
