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.

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
