Re: [qmailtoaster] 550 5.7.511 Access denied, banned sender - Office 365

Hey thanks

yeah - specifically not Hotmail/Outlook/Live, my bad - these are Microsoft 365 
Business accounts, so typically a company who has a Microsoft Online Exchange 
service



Cheers

Re: [qmailtoaster] 550 5.7.511 Access denied, banned sender - Office 365

2022-01-03 Thread Angus McIntyre 
My Linode-hosted qmailtoaster install was blocked by MSN
(Hotmail/Outlook/Live) recently.

However, it seems that they had singled out just my IP. I don't know
why; logs showed that users on my servers had sent a total of around 600
messages to about 25 distinct Hotmail etc. users in the previous year,
all personal messages from individual users. Not exactly an unstoppable
spam flood.

I jumped through the de-listing hoops, and they restored access after
about 2 days.

Linode as a whole doesn't seem to be blocked -- my IP is still
acceptable to MSN -- but you might be in a netblock that MSN have
decided to block, presumably because some bad actors have set up shop there.

You could reach out to Linode for help. It's possible that they could
either:

   a. Ask MSN to lift the block, or
   b. Allocate you a different IP or help you move to another instance.

If they can't or won't, you could consider recreating your installation
in a different Linode region and hope that that netblock isn't blocked
as well. The risk there is that you go to all the effort of moving and
then find that your new home is blacklisted as well.

I guess if that doesn't work, there's always Digital Ocean or Vultr.

The power of large companies like MSN to cause problems for the little
guys by introducing arbitrary bans is very frustrating. I understand why
they have to do it, and MSN certainly seem to be more responsive and
easier to appeal to than others ... but never knowing when you'll find
yourself blocked for mysterious reasons from one day to the next is
annoying.

I've followed their (Microsoft's) instructions, forwarded mesaage to them and 
got a response

That pointed me to https://sender.office.com/ (https://sender.office.com/) to 
delist, which I did - but it said my ip was not listed ...

It seems like a bigger block on Linodes IPs - so am in the process of chasing 
that

but ... in the absense of a resolve there, its a major - change providors - 
holy smoke - that's a big response 

So I just thought I bounce here to see if others are in same (, Linode - or is 
it a bigger,) boat ...
