GPT will not present data for that volume.  From their FAQ: "Most of the 
Postmaster Tools dashboards will only display data when there’s a 
sizable daily volume of email traffic (up to the order of hundreds) 
coming from your Authentication Domains and/or certain other conditions,

How am I supposed to remedy a low reputation?


Supposedly the only way is for the receivers to signal Google's system 
that your messages are wanted.  So far as I know that means they must 
remove the spam label (click not spam), actually open the message not 
merely look at the subject/preview before deleting it, and do so pretty 
consistently.  But it might not be reputation that is your issue, or at 
least not only reputation, it might be the content itself so you might 
have to remove or change URLs (don't use any shorteners), graphics, 
and/or words in the messages, especially in boilerplate.

Re: [mailop] Contact Google Postmaster

2024-01-26 Thread Scott Mutter via mailop
I've had domains listed in Google Postmaster Tools since 2016.  Never
gotten one lick of any information from any of those except for "No data to
display at this time. Please come back later. Postmaster Tools requires
that your domain satisfies certain conditions before data is visible for
this chart."

I eventually stopped adding domains because it didn't do me any good.

The 173.225.104.91 server has sent 68 emails to gmail.com email addresses
thus far in January 2024.  As far as I know, this block just happened
today.  Today was the first time it was brought to my attention that
messages from this server are going into the spam folder.

Again, how am I supposed to know that Google is treating this IP's
reputation poorly?

How am I supposed to remedy a low reputation?


I set up another domain on the same 173.225.104.91 server, SPF, DKIM, and
DMARC all set up (and verified with https://www.learndmarc.com).  Sent a
message to an @gmail.com address through this account, and it went to the
spam folder.

Set up the same domain on another server - 205.209.102.251 - which,
coincidentally is also an Interserver IP.  Again, verified that SPF, DKIM,
and DMARC were all set up with https://www.learndmarc.com.  I sent the same
test message to the same @gmail.com address.  Message came through in the
INBOX without incident.

What conclusions would everybody else draw?


It's frustrating because none of the too big to fail email service
providers have any way to test a sending IP or sending domain's reputation
with their service.  They block them or weigh them heavily without any
method of remediation.

It would be nice if I could check the reputation of my outbound IPs daily
and be proactive in remedying any issues with these major email service
providers, rather than have to be told by my clients that something is
amiss.  And then battle through a 2 week waiting period for the provider to
reply back or hope that someone from the provider is on MailOps and can
provide any insight.

Agreed. Example: Depending on your unix config, you can do like I did
and create /etc/mailutils.conf with this in it:

address {
  email-domain xnnd.com;
};

So that any `echo "notification" | mail aiver...@wombatmail.com` will
come from u...@xnnd.com, not u...@server32.xnnd.com.

Unfortunately I can’t say what Google or other third parties are planning to do

Is each and every message from different organizational domains sent by this 
server placed into the spam folder? Or does it affect only certain sender 
domains or messages generated by a certain MUA? You can create an account at 
Gmail and test this.

It is rumored that Gmail takes message characteristics and sender domain 
reputation more into account than IP address reputation, so maybe the issue is 
not related to the IP address at all.

You don’t have to have that much volume for data… this behavior is typical
of GMT if your domain rep is very low (IE bad/dark red) — they will stop
giving you any data at all, bc spammers with data are better spammers :)

If GMT isn’t giving you data that’s a pretty bad sign tbh. And if I had to

Why do think it has anything to do with your IP?  Do you send mail from
other IPs with the same DKIM and SPF domain?

AS people have been hinting, the reason your mail is going into the
spam folder is most likely that the recipients have been marking it as

Maybe not, but please pray tell how else I'm suppose to know the reputation
of my server's IP address?  Does Google have a public blacklist checker
that I can check?  Does Yahoo?  Does Microsoft?  I get that there's a
reason they keep these private.  But if I'm not seeing anything on a public
blacklist then what am I suppose to think?

If the IP was covered up with listing on public blacklists, then yea I'd
agree there's likely an issue on the server and a reason for the listing,
and probably a reason why Google is sending the messages into the spam box.

But as it stands now, it's only when our users notify us that their
messages are being sent to their Gmail spambox do I realize there's an
issue.  There's no rejection or anything from Google's acceptance of the
message to indicate that there is any problem.

You have to try to see this from my perspective.  How am I suppose to know
that Google is treating messages from this IP poorly?

The Google Postmaster tool is a joke for me.  Apparently you have to have

Does anybody of ebay reads here?

At work we receive mails from ebay (SPF valid) to an address that isn't
assigned to an account and can't be registered by the ebay user because
he can't access the inbox, it is root@our.domain.

I already called their customer service and they said the email address
isn't assigned to any ebay account.

We receive invoices and private messages for the ebay user here.

rcpt to is root@ on our MX, so it is not a forward/alias in our system

Is there any way to contact them so they can figure out the source of

Everyone has different experiences.  When a network is a spam sewer 
that's dumping onto your systems, then blocking the entire network is 
certainly the more sensible option.

...and then making exceptions for the few who are "lost at sea on 
the wrong boat" in said network's polluted waters and who your users 
want/need to receive communications from.  (It's terrible that the 
internet has come to this, and I remember a few people in NANAE, 
decades ago, predicting these types of problems.)

> If you want people to accept your mail, act like you do and send it
> from a network that doesn't gush spam.

I agree.

I remember setting up a Virtual Machine for a client on OVH many 
years ago.  There were major limitations on OS installation, which 
was confirmed by their technical support, so we closed the account 
and chose a different provider.  So, given that OVH runs a limited 
service (or maybe they don't do that anymore?), I'm surprised that 
they don't seem to be so stringent about their clients sending spam.

I'm not Google, but I can report that you're not in a great neighborhood.

On my network, 100% of the mail I've gotten from Interserver's network
in the past five years has been spam, the most recent last week. I've

But even people who have extensive theoretical knowledge often fail to
actually apply it when it comes to practice.

Yes, absolutely, aboutmy.email rocks!  And, is offered by a very trusted source!


Sorry, but there are issues with AboutMy.email when using multiple DKIM 
signatures e.g. RSA & Ed25519.

Re: [mailop] Extortion spam from OVH-hosted *.sbs domains

Hi all,

FYI Hans-Martin, I reached out to ovh team yesterday night to push 
your message, seems your abuse report has been processed by the proper 
team. No idea if they answered you, but at least, they have handled 
the report, and probably done the appropriate actions.


Thanks Simon!

Good to know the abuse address is not a black hole, although it would be 
a bit nicer if there were at least some feedback indicating that the 
something was done (not a bot feedback confirming receipt, although that 
would still be more than silence). Since the *.sbs spam stopped, I 
already assumed that the situation had been dealt with.


Cheers,
Hans-Martin
