Re: [mailop] Hotmail and 4.5.1 4.7.500 Server Busy with some

[Davide Migliavacca via mailop]

I'm starting to open tickets as a business customer of the the Office cloud.
Of course it has absolutely nothing to do with this and will get nothing done - 
but I understand very well the need to build some critical mass of signals that 
a problem needs attention, to get things rolling in a large organization. 
Hopefully, some QA process will correlate tickets.

Thanks for your help!

In retrospect, I suspect the word that best fits is, "Official".
 
I understand the strain on this, and am doing the best I can to get the data in 
front of the right people to get an official response, or at the very least, 
get the issue (whatever it may be) resolved.
 
BTW, somehow this thread has grown sufficently large that all my responses are 
now put in the moderation queue.

Hello Michael , 

Your support team no longer answers the tickets. We still keep getting the 4xx 
error as server busy.

When will a legal explanation come from Hotmail (or Microsoft)? 
Thank you

We are seeing this error on specific sender IPs. So “Server busy” may 
be intentionally and dependent on the sender. 
There are also many versions of this error, with at least 6 different 
AS codes. Some occur after MAIL FROM, some occur after RCPT TO, and some occur 
after DATA. 
 
Previously Hotmail said something like “We have limits for how many

You seem to have collected several images (attachments?) in the html

If you trim some of the historical messages I suspect that your

Re: [mailop] Hotmail and 4.5.1 4.7.500 Server Busy with some

[Tobias Herkula]

Hi Emre,

Some thoughts from me, I imagine a lot of people from the sender community are 
lurking on this list, but it seems to me that for most of them the initial 
hiccup of new errors from Microsoft because of the switch from the “old” 
Hotmail infrastructure to the “new” Office365 one got solved.

And then we have this new error code that has a 4.5.x and a 4.7.x in it and we 
also know that Gmails and Yahoos approach to tip somebody, to look at the 
quality of the traffic  is also via sending 4xx errors.

So perhaps the fact that you still getting these errors and the fact that 
Microsoft support does not answer anymore, is based on that quality of your 
traffic?

At least for me, one of the first rules I learned was, always clean your own 
backyard before complaining and never threat someone who can help you.

So even if you are 100% sure, that your traffic is not only legal but also 
appreciated by the recipients with their mailboxes at Microsoft. Would it 
really hurt you to double check again and perhaps be a little more picky then 
last time?

Re: [mailop] Hotmail and 4.5.1 4.7.500 Server Busy with some

[Michael Peddemors]

Hehe, IMHO the one's that threaten legal action the loudest..

"Doth he protest too much?"

Usually the ones that are going to take legal action, are the ones that 
do it without threatening to do it..


And once again, a great time to point out.. All legal precedence we know 
of, and especially in the US, always give the advantage to the party 
refusing entrance.. unless it is refused on the basis of color, 
relegion, sex.. yada yada..


Just because someone doesn't want to open the door, doesn't mean that 
you have a right to go in their house. If they don't want to accept you, 
you don't have a legal recourse to force them.. even if their decision 
is/seems arbitrary to you..


I would love to see a letter come back from 'legal' that says..

You can't come in.. "Because we said so"

Have a great weekend everyone, and make sure to take a moment of thanks 
tomorrow, and may all our future arguments be tiny ones, so that those 
kind of sacrifices aren't needed any more..


-- Michael --

PS, In my humble opinion, NEVER use the 'legal' word, or threaten legal 
action, if you want people to communicate/help you.  As soon as that 
happens, most will be obligated 'by legal' to simply cease all 
communication.  Not a great way to get a response.

Hi Michael ,

Unfortunately , it doesnt work . Outlook Support team said that 
there is

not blocking on their side .

Although the ips are Returnpath certified. Sometimes we also get 421
RP-001 (BAY004-MC2F28) errors. But mostly 451 4.7.500 Server busy.
Meanwhile, on snds I see that there is a lot of difference between 
the

For Exp.


RCPT
commands  111829



DATA

Hello Michael ,

Your support team no longer answers the tickets. We still keep getting the
4xx error as server busy.

When will a legal explanation come from Hotmail (or Microsoft)?

Thank you

Honestly, I'd suggest you assign someone with a different set of skills to work 
this issue, especially with colleagues at other organizations and in public 
fora. It's a role that requires soft skills as well as data analysis and domain 
expertise, especially when you're not clearly in the right or not clearly the 
big dog in the relationship. You wouldn't expect your SEO specialist to 
negotiate a peering agreement; let your deliverability specialists do what 
they're good at.

Cheers,
  Steve

[Emre Üst |euro . message|]

Hi Michael ,

Unfortunately , it doesnt work . Outlook Support team said that there is
not blocking on their side .

Although the ips are Returnpath certified. Sometimes we also get 421 RP-001
(BAY004-MC2F28) errors. But mostly 451 4.7.500 Server busy. Meanwhile, on
snds I see that there is a lot of difference between the number of RCPT
fields and Message recipientss.

For Exp.

RCPT
commands  111829

DATA
commands 106093

Message
recipients 1215

Thank you

Hello,



did anybody get any sensible answer from Hotmail Sender Support about the



451 4.7.500 Server busy. Please try again later from []. (AS843) 
[.prod.protection.outlook.com]



deferring a large percentage of traffic forever (even a 48 hours limit to 
retries won't help), obviously from DKIM-authenticated transactional messages 
emitted by top-reputation, SNDS-green, no-problem-whatsoever until the suspect 
recent infrastructure switch on their side IPs,

and is willing to share the love you got from them?



Sometimes the AS843 is AS844 instead.



Have a nice day!
