Microsoft/MSN Mailhosts missing IP addresses

[HN Support 0]

Hi there for a couple weeks now I noticed most reporting was going to report_spam@hotmail.com.  I started to get suspicious and so started looking into it.  It seems as though there's some Microsoft IPv6 addresses which aren't in our "Hotmail / MSN" drop-down list of the Mailhosts section our account and every time the parser hits on one of those it decides that's the source of the spam instead of continuing through the headers to the actual origin.

Case in point: www.spamcop.net/sc?id=z6456858877zb5f21cf2fa16ca99611a32e08c680ae7z  As you can see in this case it stopped at 2a01:111:e400:c47c:0:0:0:49 instead of realizing that was not the sender IP and continuing on to the more likely candidate.  Here's some more failures of this type:

http://www.spamcop.net/sc?id=z6456858882zaf7ea911350a7960e8187700288a3ff8z

I tried deleting my Hotmail/ MSN mailhost entry from within our "Mailhosts" section and recreating it didn't help.  Also here's a sample of some of the IPv6 addresses that have been incorrectly identified as the source of the spam messages in some of our submissions:

2a01:111:e400:5a6b:0:0:0:40
2a01:111:e400:5a6c:0:0:0:36
2a01:111:e400:5311:0:0:0:11
2a01:111:e400:5311:0:0:0:30
2a01:111:e400:5311:0:0:0:32
2a01:111:e400:5311:0:0:0:42
2a01:111:e400:c47c:0:0:0:49
2a01:111:e400:c47c:0:0:0:52
2603:10b6:300:2c:0:0:0:28
2603:10b6:301:0:0:0:0:27
2603:10b6:403:0:0:0:0:22
2603:10b6:403:0:0:0:0:32
2603:10b6:403:0:0:0:0:33
2603:10b6:404:109:0:0:0:18
2603:10b6:404:109:0:0:0:21
2603:10b6:405:1:0:0:0:11
2603:10b6:406:bc:0:0:0:25
2603:10b6:406:bc:0:0:0:29
2603:10b6:910:3d:0:0:0:39

Also please note that whenever all the Microsoft / MSN IPv6 addresses in the message header ARE listed in the current Microsoft / MSN dropdown those messages are correctly parsed and the source of the spam message positively identified.  However this seems to be only 1 out of every 10 submissions which means I'm cancelling the reporting of 9 / 10 submissions at this point.

Please advise.

Wants to erroniously send report to report_spam@hotmail.com

spam needs submitting report_spam address has been requested by hotmail for SpamCop reports

There is a problem that a lot of these are legacy issues and just go to a bit-bin.

You can submit spam to "abuse [ at ] microsoft [ dot ] com" from your email account where you actually received that spam

[HN Support 0]

The problem, petzl is not that the parser is generating a report addressed to the report_spam@hotmail.com address but that it is doing so INSTEAD of creating a report addressed to the actual ISP where the reported spam message came from, making the whole exercise relatively pointless.

What's Microsoft going to do about a spam that originally came from somewhere not in their control?  Nothing.  And then at the same time the ISP of the spammer isn't getting the notification it needs to take action.  That's the real issue here.

For example in the link you put into your reply the origination IP address of that spam message was most likely the 74.202.231.63 IP address listed in the headers.  When spamcop is parsing correctly it would most likely have found that it should address the report to security@level3.com, the abuse email address on file for the ISP in charge of that IP address.  As you can see at the bottom of that parse job that's NOT where it's addressed to and that's a fail.  Microsoft is not in charge of that IP address and therefore has no jurisdiction to correct the issue.

HN Support... exactly right.  It's a parser error.  

The parser discarded the most important header...
Chain error HE1EUR02FT053.mail.protection.outlook.com not equal to last sender received line discarded

Hotmail changed its handling of incoming email about a week or two ago.   It is messing up the parser.
Now every spam I report goes to report_spam @ hotmail.com.

That's worse than useless, it wastes the time of abuse dept at hotmail.

Until the parser is fixed, there is no point in me reporting the spam I get in my hotmail account.

Initially I was cancelling these but I've now realized it's possible to uncheck the report_spam@hotmail report, check the 'user report' option under it, then fill in the abuse address for the ISP who's in charge of that particular IP address.
You can find this by looking in the headers for the point at which a non-Microsoft server has handed off the messaging to a Microsoft server and running a whois on the IP address of that hand-off server. From your link above this is the relevant section:

Received: from mail1.listingbookmail.com (74.202.231.63) by
 HE1EUR02FT053.mail.protection.outlook.com (10.152.11.109) with Microsoft SMTP

Doing a whois 74.202.231.63 | grep Abuse gives us the following results:

OrgAbuseHandle: TWTAD-ARIN
OrgAbuseName:   tw telecom Abuse Desk
OrgAbusePhone:  +1-800-829-0420
OrgAbuseEmail:  abuse@level3.com
OrgAbuseRef:    https://whois.arin.net/rest/poc/TWTAD-ARIN
RAbuseHandle: TWTAD-ARIN
RAbuseName:   tw telecom Abuse Desk
RAbusePhone:  +1-800-829-0420
RAbuseEmail:  abuse@level3.com
RAbuseRef:    https://whois.arin.net/rest/poc/TWTAD-ARIN
network:Abuse-Contact;I:abuse@twtelecom.net

So then you fill in abuse@level3.com into the blank 'user' field and submit that, instead.

It's open season on Hotmail users until parser gets fixed and can correctly identify source of spam.

Here is another example of mis-directed abuse reports...

Sometimes reports get sent thru to abuse@level3.com

About 25% reports get sent, and 75% reports are disabled.
 

I'm not sure why but definitely games are being played by this ISP.

HN Support,

Everyone can uncheck report_spam @ hotmail, but not everyone has the option to fill in user field.  That's a spamcop premium user option.
 

Also, Filling in the optional user report field with the correct abuse email does not contribute to the blacklist for that spammer.

Or Hotmail corrects the changes they made

It is not feasible for SpamCop to adjust the parser to deal with every change made to other's email software.  Hotmail, among others, are not really too interested in how they affect other applications. Their interest is in providing (free) email service to their clients, so the client data, usage, networks are available to scrape.

#metoo - I sometimes have unwanted email arrive at my outlook email account that apparently arrives from yahoo or google, yet the parser decides to use the MSN reporting address. It's annoying having to do so, but when I spot such an email, I uncheck the report to hotmail, and fill in an appropriate abuse address for user submitted reports.

possibly different IP's are run by different owners?

[Kewl 0]

It's been a over a month and since I've been able to report spam arriving in my hotmail account.

All reports would be sent to report_spam@hotmail.com whether they had anything to do with source of spam or not.

I refuse to bother their abuse dept with frivolous reports.

[HN Support 0]

Actually the way I'm reading things Microsoft is the cause of the problem in the first place so in addition to manually determining and reporting to the actual source ISPs of the spam messages I'm also leaving the check mark on to submit to the incorrect MS spam reporting address as well.  The intention there is for them to notice the error and as a result put some action on to fixing their IPv6 rDNS entries to conform with the standard.

Can someone confirm if report_spam@hotmail.com really works?

[oZoneCapHill 0]

Let me start by saying I am having tons of issues with Outlook online / Hotmail and some of the issues may be MSN issues, but someone really needs to look into it since I report all my Hotmail spam here and it no longer works very well. Micro soft is slow to fix issues but they will address them if you write up the issue on the Microsoft feedback forum ( https://answers.microsoft.com/en-us/outlook_com/forum/oemail-osend/emails-headers-have-multple-issues-when-trying-to/7d5c2315-38ae-4dcf-9e29-e1d64932b65e ).

Issue 1:

I thought maybe my mail config was messed up and I deleted and tried to redo my mail config and all I get now is:

Headers mangled

It appears that the sample you provided has been altered.  Often, extra
line-breaks are inserted by your software in an invalid format.  Part of
the reason for this proceedure is to ensure that you and your software are 
submitting spam in an error-free format.  Please review the relevant FAQ 
for your software and ensure you are following a proceedure which returns 
intact spam content to SpamCop.

In this sample, the problem was found near the line:
via BYAPR05CA0039.NAMPRD05.PROD.OUTLOOK.COM; Sun, 5 May 2019 05:19:37 +0000

Issue 2:

Now when I report Outlook online / Hotmail I am getting a chain error:

https://www.spamcop.net/sc?id=z6543836809z438812bd7b6c2eaf52d5d36941b1cef2z

just keyword headers " sender IP is " without quotes which in this case is
52.69.50.108   abuse[AT]amazonaws.com country Japan
child porn spammer has moved to another free throwaway AWS web account
AWS don't accept abuse reports from SpamCop and prove to me they are morons from space.
Most countries use monkeys, using morons is one better? 
AWS will send your report to spammer  child porn spammers but they will opt you out of their spam.
with hotmail spam you need to either "forward as attachment" put the sender IP in body with abuse address.
If   "forward as attachment" is not available copy and paste Body and Text into forwarded message
AWS require this method.
above paste put in source IP then two blank lines

SpamCop can no longer decipher Hotmail headers

Hey oZoneCapHill, 

With all Outlook/Hotmail mail, the "original"/Classic or "new", was BETA, now referred to a "production" by MS, always remove the first:

Received: from xxx all the way through to +0000 

In the example you've submitted it's as follows:

Received: from AM5EUR02HT165.eop-EUR02.prod.protection.outlook.com
(2603:10b6:a02:a8::18) by BYAPR02MB4678.namprd02.prod.outlook.com with HTTPS
via BYAPR03CA0005.NAMPRD03.PROD.OUTLOOK.COM; Sun, 5 May 2019 11:38:40 +0000

The explanation provided by SpamCop Admin (as to why it's optimal to do this), was/is:

"A couple of years ago Hotmail had to give up two /16 networks they were using (33,554,432 IP addresses) as they were not assigned to them. Microsoft had to quickly reconfigure their network and used IPv6 to do so. Unfortunately when doing so, they did not do it carefully and make sure they had full name resolution through out the network, where the forward and reverse dns on each server matches.  This means we can't trust their headers and will often take them as the source of the spam."

• Using the SC URL you've submitted I removed the above "Received, etc > +0000", ran it thru SC, using a  SC account with MailHosts , this is the result:

https://www.spamcop.net/sc?id=z6543932098z889c38dc916f2b763336930b55cf1af9z

****

To address the MailHosts issue, (imo) the fastest, most successful & least painful (for you) solution, is to contact SC admin, provide details & ask for their assistance. Many folks have either had trouble setting up the hosts & or, having modified previously setup hosts, find the mods have "buggered" up spam being parsed successfully... 

****

Back to the SC URL you've provided:

The 2nd issue (when the SC generates a result) is "no links detected", irrespective of the fact there are indeed embedded links... There's various good commentary, across SCF, as to why the parser may not detect links & why this is less of an issue than the parser not being able to parse the spam at all.

I think from memory, these posts also contain: "try x", "try y", solutions, in some of the posts.

With your specific URL, I'm unsure if the reason, is a failing by SC parser, or, the actual formatting in the message body.

Again, with your specific URL, the links resolve to: 

111.90.150.137, AS 45839 (Shinjiru Technology Sdn Bhd), abuseATshinjiruDOTcomDOTmy

Condensing all of the above: with working hosts & modifying the spam, before presenting to SC parser, it would be good to see if there's better results. 

Cheers!

G🦗H
