Hi Michael,
Is there a reason why unused or newly allocated blocks seem to be automatically
blocked for Outlook/Hotmail ?
We were recently allocated a new /22 for customers and every one of the
customers who uses their own mailserver is getting blocked by MS, no spamming
no history just blocked.
I realise that some systems work on reputation, but how can you get a good
reputation if you can’t send the email in the first place ?
Is there some reason why whole blocks are just blocked by MS ? this seems to be
the case with us.
What can network operators do to alleviate this problem for our customers ?
The customers look to us for a resolution as their provider, but apart from
request that an address gets unblocked there is nothing more we can do, and
unfortunately they don’t see it that way.
It’s unreasonable for us to think that we have to put in 1024 requests to get
IP’s unblocked, which would all be rejected for mitigation initially, then you
have to reply to the email and request again to have a chance of it being
unblocked, that seems to be about a 50% hit rate for us.
Any thoughts on how to resolve this issue in a more efficient way would really
be greatly appreciated.
Thanks
Paul

"Pre-emptive Accommodation" is, I believe, the correct term.
And yes, it does help if it's before traffic actually starts.
Glad it got unblocked.
Aloha,
Michael.

Update: after submitting the form for the 3rd time, it seems that the IP got
unblocked at last.
By the way, asking for "new IP space" form did not work.

We have had the same problems with Microsoft for some time now with a new block
we have, every IP is getting blocked for no reason, they say they have
unblocked them and they still treat received emails from those IP’s as spam.
They won’t unblock the whole subnet either.
Not sure what else you can do, and the problem is the customer sees it as your
problem when it’s Microsoft being over sensitive or something.

We've been having the same experience for months now. Not always, but way too
often.

Hi,
2 days ago one of our IPs started getting an AS3150 block when sending to
Hotmail/Outlook.
Which is very weird, as complaint rate and bounce rate are way below what
Outlook publishes as their official requirements.
After submitting their delivery support form, we get the automatic email saying
that the IP has been mitigated: "Our investigation has determined that the
above IP(s) qualify for mitigation. The block has been lifted, and the IP(s)
have been granted increased daily sending limits."
However, the IP still stays blocked! After replying to that email, we get a
copy-paste reply from Outlook.com support saying that "As previously stated,
your IP(s) do not qualify for mitigation at this time."
???
Alright, we repeat the process the next day, with the same results - initial
email says that the IP has been mitigated, that doesn't work and the IP is
still blocked, and Outlook.com support says that the IP is not eligible for
mitigation.
Asking to escalate to T3 did nothing.
Has someone else experienced this? What to do in this situation?
P.S. if anyone from Outlook/Hotmail are here, here is the ticket number:
SRX1410467394ID. I would greatly appreciate any help or insight into this.
