It is being actively discussed internally.
That’s all I can say at this point.

Hi Benjamin

Im seeing some weird stuff too - a customer who hosts his email domain on O365, 
sent a few hundred thousand tests on our IP to his own domain, no hotmail or 
outlook addresses involved, and yet the test mailings show up on SNDS and his 
IP reputation is thrashed. The irony is he sends mail on behalf of an MS 
product. Im not really sure where to go with this from here, as our insisting 
tickets are being ignored.

The law of unintended consequences?

Hi,

A reputation has to be evaluated on the long term of course, however the older 
the "action" was, the less importance it should have.

Another tricky part of "reputation", that we witnessed recently with Microsoft 
particularly, is that there are "links" created along with the reputation.
We know that Gmail takes into account a lot of things, not just headers, and 
keywords, and domain names, and IP addresses, and behavior of users, but also 
interactions between those, and other stuff.
We guess Microsoft does something similar.
So these "links" could be tricky, as we recently had Brazilian clients moving 
out to another ESP. They had dedicated IPs. We forbid them to send crap (that 
might be a reason why the left), but now they're free again, so crap it is.
The dedicated IPs, not sending anything anymore, have been blocked, as noticed 
in SNDS.
We suspect that because they are using the same domain name now with the new 
provider, than they did with us previously, and that now they are spamming from 
totally unrelated IPs, our IPs have been impacted. The fortunate part is that 
there's nothing going out of these IPs, because if we immediately re-attributed 
them to another client, maybe this client would have issues, and we would be 
investigating what he was doing wrong while it could be not his fault at all.

Maybe that could be solved after a few insistent tickets to the support.

Cheers,

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.

It’s not alone at all. dnswl.org  has a *very* long memory. 
Oldest history entry in the internal blacklist (DNSWL Id 666) is 

[postgres@dnswl]# select dnswlid, histdate from tblhistory where dnswlid = 666 
order by histid limit 1;
 dnswlid |  histdate
-+-
 666 | 2010-11-20 17:35:39

The oldest history overall which still exists:

[postgres@dnswl]# select dnswlid, histdate from tblhistory order by histid asc 
limit 1;
 dnswlid |  histdate
-+-
 | 2006-12-19 19:33:36

However, the IP still stays blocked! After replying to that email, we get a

Alright, we repeat the process the next day, with the same results - initial

still blocked, and Outlook.com support says that the IP is not eligible for

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:

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

Thanks, Brian. That's not a bad idea. Worth a try, anyway.

Re: [mailop] Weird problems with mitigation at Hotmail/Outlook

[Brian Curry]

What might be going on there is MSFT lifts the “block” but doesn’t change any 
thresholds/limits the IP is still susceptible to.

You may want to prompt the robots to give you the “new IP space” form to 
provide expected volumes from the IP, and see if MSFT will adjust thresholds on 
the IP. That has worked in the past for me, along with the mitigation.

Seen this also recently (past couple of weeks at least). "Block has been

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.

[mailop] Weird problems with mitigation at Hotmail/Outlook

[Edgaras | SENDER]

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.
