Fair point:

The sending domain is annbauer.com, mx is hosted by mx.oustrencats.com.

IP addresses:

root@giraffe:~# host mx.oustrencats.com
mx.oustrencats.com has address 50.116.29.164
mx.oustrencats.com has IPv6 address 2600:3c00:e000:323::1

I am not positive on the HELO string, as postfix isn't logging that, but 
I would guess it is mx.oustrencats.com with envelope from x...@annbauer.com


Again, DKIM, SPF, DMARC and reverse DNS are set up properly enough to 
get mail delivered to google.


Not sure what you mean about domains referenced in the body, someone 
contacted my wife and she was replying.


Thanks!

I'm not sure why my server defers on 554, that's the default config for

Usually providers provide info on the block, with details on how to get

[mailop] Trouble sending to sympatico.ca

2022-07-31 Thread John Gateley via mailop

Hello,

I just got a bounce from sympatico.ca that I don't understand:

Access Denied)
Jul 31 04:20:41 giraffe postfix/qmgr[2366]: 841B53C6CD:

It had been in the queue for a week or so, and finally bounced.

I don't see any details in the error message.

I have a very small mail server (just my wife and I) but it is 
configured with reverse DNS, SPF, DKIM and DMARC. I can send to the big 
players without bouncing or ending in the spam folder.



Any ideas? Thanks!

[mailop] Microsoft/Linode issue resolved

2022-01-23 Thread John Gateley via mailop

Hi y'all,

I resolved my Microsoft blocking my Linode IPv4 address issue. I posted 
several times here as it

was happening, so this is a recap:

Microsoft's mitigation process is fragile and complex, perhaps 
intentionally.


1. It requests forwarding the bounce message. My mailer (standard 
Dovecot + Postfix) adds
a couple of attachments to the message. Microsoft will reject messages 
with attachments

and not do anything. So you must remove the attachments before forwarding.

2. Microsoft's mitigation process handles both Office365 issues and 
outlook.com etc issues.
They seem to make no distinction in the error messages. My bounces 
indicated it was an
Office365 issue, but I followed that process several times with no 
result. Finally, I filed
an outlook.com delisting ticket, and after some back and forth they 
delisted me.
I wish Microsoft had a better system for communicating WHICH platform is 
blocking and

the process for that platform.

3. After several tries, the Office365 mitigation process just stopped 
working. After the forward
I receive an email saying "we will respond in 24 hours". The first few 
times, this incuded
a link to the Office365 delisting process. But at some point, Microsoft 
stopped responding.
I would get the "we will respond" email, but never anything more. It was 
blamed on huge
traffic from Linode, but that wasn't the case (as it happened several 
times over many days

and I NEVER got a response).

I truly appreciate the help I received from this list, and it is 
fantastic that there are Microsoft,
Linode (and other companies) people here contributing. That made it 
easier for me to find the

solution.

Linode has a mediocre reputation (I think this is undeserved) for IP 
cleanliness. I contacted
Linode and they offered me an IP address known to be clean w/r/t 
Microsoft filtering.
Changing a mailer's IP address is a dramatic operation so I haven't yet 
decided to go through
with this. But they were professional, helpful, and I have been using 
them for 15+ years,

and probably close to 10 on my current IPv4 address.

The reason I think their reputation is undeserved: I asked for better 
hosters, and did receive
some recommendations. I checked these, calling one and speaking with 
Sales, and reading
the websites of the others. They had no special restrictions or filters 
regarding email, the
sales person I spoke to just said "we don't allow spammers". My guess is 
that they are cleaner
IP addresses mostly because they are smaller, and spammers don't flock 
to them.


Linode has been pretty good to me, and very responsive. There seems to 
be a pile-on attitude

regarding them as mail servers, and in my opinion it is undeserved.

Thanks to all who contributed and helped me!

John

Re: [mailop] Microsoft/Lindo - junked,not blocked

2022-01-17 Thread John Gateley via mailop

Hi Alex, and thank you for responding.

I went to that form, entered the info, got the confirmation email,
and then when I do step 3 to unblock, it says:

The IP address in question is not currently blocked in our system. 
Please refer to the email message you received from Microsoft and follow 
the steps it suggests.


I had done these steps several times (with the same results) several 
days ago, but stopped when

the "forward" stopped getting responses.

Reading between the lines, I think the response to the forward is a 
standard "click here"

message without any actual investigation, and just takes you to that link.

The full error message (sorry, should have put this in before) says:

microsoft-com.mail.protection.outlook.com[104.47.54.36] said: 550 5.7.511
Access denied, banned sender[50.116.29.164]. To request removal from this

This looks like Outlook to me, not Office 365. I will try the support 
ticket referenced at the

tail end of the Office 365 process.

Thanks again for the response.

Some of us have limited enthusiasm for providing free consulting to

My opinion about Linode is that it's not the worst but it's far from the best.

I use a small hosting provider called Tektonic that nobody has ever heard of
because nobody sees spam from them.  They have a fairly hard-nosed outgoing
mail policy, it all goes through "transparent" filters unless you can give
them a sensible reason to turn the filters off.



I am not really an "organization", just a long time IT person who has 
hosted my own

server for many years.

It is true I do not manage my user's behavior: my only user is my wife, 
and it would

not lead to a happy marriage if I tried to manage her behavior.

But the server only hosts the two of us, no mailing lists or other 
users. It is incredibly

small volume, and we don't bulk email anyone for any reason.

Thank you VERY much for the Tektonic recommendation.

This recent incident with Microsoft is a sore spot and so far a

I have also seen that for other hosting platforms (AWS for instance).

I have never seen someone say "platform X is fantastic at hosting

Is there a platform that doesn't instantly provoke the response:

Re: [mailop] [EXTERNAL] Microsoft IP Filtering - sort of full details

2022-01-12 Thread John Gateley via mailop

The bounce message is immediate.
The response to the forward is immediate.
I have gotten the next step after the forward twice, once it took 4 
hours, once it took 6.

Both of these are in the past 3 or 4 days.
It's now been 12 without that.

I don't think you can blame this on a linode IP delaying responses, 
since the response when I forward is immediate.

This is something on the Microsoft side.

As said below, I will try again tomorrow with a different from and to 
address.

No comments on Linode spamming, but looking at this, have to comment.

host enlogic.gr
enlogic.gr has address 172.105.85.167
enlogic.gr mail is handled by 0 enlogic-gr.mail.protection.outlook.com

host 172.104.233.127
127.233.104.172.in-addr.arpa domain name pointer extmail.enlogic.gr

If microsoft thinks that the email server for that domain is their 
infrastructure, why would they accept any email from outside MS with 
that domain, if it isn't authenticated.


The rejection message looks pretty clear.. banned sender.

What is the address in the MAIL FROM, it looks liek @enlogic.gr?


The mail is being sent by 172.104.233.127, enlogic.gr is the recipient.


I too am having this issue, (also a linode customer, but no support 
tickets from me). I'll be posting more details later.

Re: [mailop] spamhaus blocking Linode IPv6 (2a01:7e01)

It's not a Spamhaus problem. Linode is beyond stupid. Linode has over 
four billion /64s. The rest of the Internet treats a /64 as a single

as a minimum.


If you're a Linode customer, demand a /64. Point them here: 
https://datatracker.ietf.org/doc/html/rfc7421




There's some questionable info on this thread. Linode uses SLAAC to 
assign a single IPv6 to each linode, but gives out /64 blocks on request

https://www.linode.com/docs/guides/linux-static-ip-configuration/

They recommended to me to use a /64 address and not the SLAAC address 
for my servers, including the mail server. No charge.


You don't have to demand, just submit a support ticket as the docs say.

I ran into this problem a couple of years ago, switching to the /64 
block resolved it. It wasn't a huge deal.

Re: [mailop] Google not sending DMARC Aggregate Reports

2021-10-08 Thread John Gateley via mailop

I checked, last one I received was some time on Oct 2nd.
I am getting others though.

Weird.

Hello Everyone,

Google abruptly stopped sending DMARC Aggregate reports.  No RUA 
reports have been sent since Oct. 3rd.  Seems strange that not much 
has been said about this issue.  Can someone offer any information on 
why this is happening?


I would appreciate any insight.

Thank you,

[mailop] Microsoft contact for misclassified spam issue?

2020-08-07 Thread John Gateley via mailop

Hi y'all,

I am using a user auth SaaS, and one of the actions it performs is 
sending "Reset your password" emails.

These emails have links inside for users to reset their passwords.

Delivery to most places is working (Google etc.) but Microsoft Office 
365 users are consistently getting their emails in the junk folder.


I have tried everything I can think of... is there a contact at 
Microsoft here that could give me a hand?


Thank you

John

[mailop] Messages from small personal SMTP server being marked as junk by Google

2020-01-23 Thread John Gateley via mailop

Hello,

I have run my own mail server for about 20 years.
It is postfix, and has DNS, SPF and DKIM set up correctly.
It is very small, just serving mail for my wife and I.

She recently sent email to a group of students for a class she is 
teaching, she had

e-mailed none of them before. Most of them had gmail addresses, and most, if
not all, had my wife's e-mail sent to junk.

There were 19 recipients on the To: line.
15 of the recipients were gmail addresses.

Any ideas why? Or how I fix it?
The mail server is too small (much much less than 100 messages per day) 
so I cannot

check Gmail's tools for this.

Thanks

John

Also, it's hard to optimize for the servers that send us one message a 
day.  I've argued before that we should
have better handling for the smallest servers (whitelist the first 5 
messages/day for low volume IPs, for example),
but the total volume compared to the effort against the major spam 
campaigns, it's hard to get that high
enough on the priority list.  We did make some changes for that for 
smtp time blocking, but it doesn't move any of
our numbers because the number of messages affected is tiny... and 
when you're talking about IPv6, even small

numbers like that can result in large enough holes for spam campaigns.



Hi Brandon,

Thank you for responding here. I would love if Google could support the 
smallest servers better.
I run my own mailserver for my wife and I, and usually it is okay. But 
the tools available from
Google require hundreds of messages a day, and we probably hit 20 on a 
very active day.


And a very technical question: I changed my SPF records to allow a 
second server, and that
seemed to change my reputation - messages then started going to spam. Is 
that the cause?
(I was updating to a new version of the OS, and the process involved 
moving to a new
server and then back again.  I need to do this upgrade again sometime 
and don't want to

destroy my reputation again).

Again, mostly, thanks for jumping in here.

John
