Re: [mailop] Bitninja

[Alexander Burch]

I have now received 6 followup emails from their "security adviser" who
strongly believes I need to schedule a 15 minute call with him to fix the
problem. That seems excessive, right?

I dug through all of their countless reports they've sent to us over the
past few months and I found one small instance of abuse, but overall the
abuse reports are very inaccurate and seem like they are just a ploy for
selling a service.

Thanks,
Alex

[mailop] Bitninja

[Alexander Burch]

Is there any reason I should think Bitninja is reputable? They send us
complaint reports all the time and I often investigate them but they seem
totally erroneous and never lead to any real spam activity.

Then they send me a notice they've blacklisted our IP and that we should
consult them for services to help keep our IPs clean.

It seems completely untrustworthy, but maybe I'm wrong? Is there any
legitimacy to bitninja?

Thanks,
Alex

[mailop] Microsoft 2.6.0 ... 2.1.5

[Alexander Burch]

A typical Microsoft successfully delivery looks like this at the moment:

*250 2.6.0* <201253301423436.4896.423455598.sw...@senderaddress.com>
[InternalId=33775622235527, Hostname=
DB5E4H82HT026.eop-EUR03.prod.protection.outlook.com] 26376 bytes in 0.420,
61.327 KB/sec Queued mail for delivery -> *250 2.1.5*

It begins with 250 2.6.0 and ends with 250 2.1.5. Why are there 2 status
codes? Does the second one provide additional context, maybe something like
"not blackholed"? Or is it just repetitive and therefore insignificant?

Thanks,
Alex

Re: [mailop] Yahoo throttling 421 4.7.0 [TSS0...

[Alexander Burch]

Thanks so much Matt. Did you make any adjustments on your end or was it
just a matter of contacting Yahoo?

Any tricks with contacting Yahoo? I already did so this week but hit a
stone wall. Are there any particular phrases that get you past the
robots/canned responses?

[mailop] Yahoo throttling 421 4.7.0 [TSS0...

[Alexander Burch]

We've seen a big uptick in Yahoo throttling in the past 7-10 days with this
typical message:

421 4.7.0 [TSS04] Messages from XX.XX.XX.XX temporarily deferred due to
user complaints - 4.16.55.1; see
https://help.yahoo.com/kb/postmaster/SLN3434.html

This seems to be happening fairly indiscriminately across various IPs, and
I know for certain none of them have high complaint rates.

Yahoo's postmaster page says "The error is temporary. We encourage you to
retry sending emails 4 hours after encountering the error."
https://help.yahoo.com/kb/postmaster/SLN3434.html

We have backoffs at Yahoo, but they certainly don't last for 4 hours.
Should that be taken literally? If we see that error should we backoff
sending on that IP for 4 hours? That seems a bit extreme. Can anyone offer
perspective on the backoff intervals they use here?

Thanks,
Alex

[mailop] AWS bring your own IP

[Alexander Burch]

I had the same initial concern that "bring your own Ip" != "bring thousands
of your own IPs"


However, that page explicitly lists email senders like ESPs as a use case:

"Bring Your Own IP is also useful for applications such as commercial email
services that rely on IP address reputation to allow traffic from your
endpoints to reach intended recipients."


I can't say for sure without speaking to an AWS rep first.


The concern about ASN announcement is a good question. That's what I'm
hunting after - "what traces of AWS would still be in the message
fingerprint and how toxic would they be?"


I wonder if this is true. If we own the IPs and have our own ASN wouldn't
our ASN be used?

[mailop] AWS bring your own IP

[Alexander Burch]

Traditionally, ESPs have been unable to use AWS for sending mail because
AWS IPs have very bad histories of being used for spam (among other
reasons). I believe most ESPs are running their own servers for email or
using a managed hosting service of some kind that allows them to use
private IPs/rent private IP ranges. However, AWS just announced a "bring
your own IP" program that caters to ESPs. This lets you use your privately
owned IPs on AWS infra:

https://aws.amazon.com/about-aws/whats-new/2018/07/announcing-bring-your-own-ip-for-amazon-virtual-private-cloud-preview/

I think this could cause cause a shift in the way ESPs manage their mailing
infrastructure. This makes it much more viable to send mail from AWS, which
in turn is much more scalable than managing a colo machine or paying a
managed hosting service and probably a lot cheaper.

I'd love to hear opinions on what negative effects anyone anticipates of
using AWS + private IPs for their mail infrastructure.

Thanks,
Alex

[mailop] Recent "banned sending IP" errors when sending to Microsoft

[Alexander Burch]

Yes we started seeing these maybe 6 weeks ago. They are very common,
probably popping up on 3-5 IPs per day. We have to manually delist them
which is a pain. Seems like a very silly system because there is no
correlation between the block and troublesome senders that I can find.

What I am wondering is, if Microsoft merged Outlook an Office365 infra,
what are we still seeing specific blocks specific to Office365? There is
clearly a different Office365 anti-spam system running independently of
Outlook to some extent.

Thanks,
Alex

[mailop] Email issues to outlook.com and hotmail.com this afternoon/evening

[Alexander Burch]

I've seen this too. Started earlier this week (Feb 19th). A big uptick in
the number of "4.7.500 Server busy. Please try again later..." responses
from Hotmail. I was assuming they were reputation related (spike in
complaints and/or sending volume maybe). But they seem to be especially
aggressive over the last few days. Maybe because Mr. Wise was busy at
M3AAWG.

Thanks,
Alex

[mailop] Yahoo Mail Servers having new issues?

[Alexander Burch]

This is an old thread but seems to be an ever present issue, at least for
us.

Essentially, Yahoo just quits the connection after EHLO. This happens very
often on certain IPs. The basic dialogue is below. Has anyone ever
determined why Yahoo does this? Is it a reputation issue? Opening too many
connections or sending to fast? It seems like historically Yahoo support
has not been able to help with this if I'm reading correctly. What to do
then?

[mailop] increase in deferrals/throttles at icloud/me/mac

[Alexander Burch]

Has anyone else seen a big increase in the time it's taking to delivery to
icloud/me/mac addresses?

I'm not seeing a ton of irregular bounces, I'm just seeing that the SMTP
handshake is taking quite a while. And I'm seeing this with many different
IPs.

I'm wondering if they are making some changes as they incorporate Cloudmark
into their backend. Just a guess. Has anyone heard anything along those
lines?

Thanks,
Alex

[mailop] 5.7.1 bounce codes

[Alexander Burch]

5.7.1 codes are used exclusively for policy blocks (IP blacklisted, content
deemed spammy etc).

Gmail uses it for DMARC rejections.

Hotmail also uses 5.7.1 when an IP is outright blocked.

This type of bounce confuses me a little. It certainly shouldn't be used to
mark the recipient as invalid, and it shouldn't be treated as a soft bounce
either (using the traditional 3 strike rule). But most ESPs have 5.7.1.
listed as a "hard bounce" in their documentation. That seems wrong.

Of course you will need to address the actual block/policy issue, so these
bounces are important to monitor. But the bounce code shouldn't affect the
recipients "status" in any email system, which is what a "hard bounce"
would do.

My conclusion is that these types of bounces should have no bearing on the
recipient's "status", and they shouldn't be classified as "hard" or "soft",
but rather ignored.  Has anyone else come to a different conclusion?

Thanks,
Alex

[mailop] Certified Senders Alliance

[Alexander Burch]

What is the general opinion of the Certified Senders Alliance? Does anyone
find it impactful for delivery? They offered to let us join without any
vetting, just sent us a bill for $___ without any questions. If there is no
vetting process I have a hard time seeing how it would validate any sender
as trustworthy.

[mailop] Proofpoint contact?

[Alexander Burch]

Does anyone here have a contact at Proofpoint? Their sales team is sending
spam with a purchased list. I think that, as an anti-abuse company, they
should be aware of this so that those responsible can be corrected.

And, when we deny service to them for using a purchased list, they should
be polite and respectful that we are enforcing our policies, not rude.

[mailop] unique/shared public DKIM keys per domain?

[Alexander Burch]

Do major ISP check the public DKIM key for reputation metrics?

For example, an ESP might use domain1.com, domain2.com and domain3.com to
sign messages for different reputation pools.

If these domains all have the same public DKIM key will this "blend" their
reputations in any way, namely at Gmail? Will Gmail see the 3 domains use
the same public key and link their reputations?

Is there any advantage of using a unique public DKIM key for each domain to
keep the reputations compartmentalized?

[mailop] Yahoo Errors

[Alexander Burch]

We are seeing this too, on a whole slew of IPs. We are getting "451 4.3.2
Internal error reading data"

I'm guessing it's going to just clear itself up after a few
hours/overnight. Anyone know why this happens? Seems to pop up here and
there every so often, but I don't think it's reputation based.

[mailop] mailop] Hotmail is blocking our mail relay IP range

[Alexander Burch]

We have seen similar blocks recently pop up at Hotmail in the past few days
on dedicated IPs of very legitimate senders whose lists are sparkling opt
in.

Hotmail accused these senders of Namespace mining, which might be the same
category as what you are seeing as "harvesting". This just isn't true. It
seems like they are changing some things up, resulting in some false
positives.

Re: [mailop] Hotmail "Organization queue quota exceeded."

[Alexander Burch]

We are seeing this too. It seems specific to the new Hotmail/Outlook MX
records (versus the old hotmail.com mx's). With domains like hotmail.co.uk
that only have the new MX records it's unavoidable.

Our connections limits are extremely conservative, so I'm not sure why this
is happening. Anyone else made contact with Microsoft yet?

Re: [mailop] mailop Digest, Vol 119, Issue 5

[Alexander Burch]

You are right that  would create many queues
connecting to different MXs. That could results in 10+ queues all
connecting to the same MX, like hotmail.de,hotmail.es,hotmail.fr,hotmail.it,
hotmail.se which all use hotmail.com's mx records and potentially flood the
same mx with too many connections.

You can avoid this by using a domain macro that matches all Hotmail/Outlook
domains and then uses "queue-to" to roll them into a singe queue (
directive). It's ideal to have all these domains rolled into one queue, so
you have more control over how many connections they are collectively
opening to the mx at hotmail.com which are shared by many domains, rather
than having 10-20 independent queues all connecting to the same MX and
possibly overloading it.

When using "queue-to", "Use of the route directive is required." per the
pmta manual. The "route" directive forces all those domains in the macro to
use one static MX record. So, yes, with that setup all Hotmail/Outlook
domains get rolled into one fixed MX record, with "route hotmail.com" or
whatever domain you choose.

If you were to ditch the "queue-to" directive and just use something like
you suggested:  that would potentially open too many
queues to the same MX's and at times overload them with too many
connections? Or maybe with Hotmail/Outlook's new setup of unique MX's for
each domain, this doesn't matter anymore?

Maybe this thread belongs in the PMTA Forums instead. I posted there:
https://forum.port25.com/powermta-support/hotmail-co-uk-bounces/

Alex

Re: [mailop] mailop Digest, Vol 119, Issue 2

[Alexander Burch]

I can confirm what Allen said will fix the issue. Just take hotmail.co.uk
out of your rolled up mx config for Microsoft domains.

I wish powermta had a more resilient way to handle mx changes.

Thanks,
Alex

[mailop] hotmail.co.uk bouncing entire IP range with "mailbox unavailable"

[Alexander Burch]

Anyone else seeing issue with hotmail.co.uk bouncing messages with this
code:

"550 Requested action not taken: mailbox unavailable,"

That's usually reserved for invalid email addresses, but they are bouncing
100% of the messages we send them on on of our IP ranges with that code.
Just started this morning.

Thanks,
Alex

[mailop] AOL whitelists

[Alexander Burch]

I wanted to reach out and see what other people have to say about AOL
whitelisting on this thread.

It seems AOL's approval process/standards for approval are fairly erratic.
They often decline whitelisting requests for IPs that have really excellent
reputations. I honestly could not find any reason to be concerned about the
traffic on the IPs being submitted (moderate sending volume, complaint
rates less than 0.01%, open rates above 30%, bounce rates safely below 1%).

But then randomly they will approve a request that seems no different from
the others, and I'm not sure what was different.

I'd love to hear from others on this thread how they handle AOL
whitelisting from the when you are managing lots of shared IPs. Are there
any tricks or pointers you have?

Thanks,
Alex

[mailop] looking for a good backchannel to share/lookup problem customers who are abusing ESPs

[Alexander Burch]

I was wondering if anyone had good suggestions for a backchannel or forum
where we can post information about really bad spammers who have abused our
platform and are likely "doing the rounds". These are usually really nasty
affiliate rings that are difficult to identify because they have hundreds
of sites and are very good liars :)

I would love to tell others that a certain user/site is causing major
problems, and also look up information when we have someone that is likely
about to abuse our services.

Thanks,
Alex
