Subject: [EXTERNAL] [mailop] Problem delivering to protection.outlook.com



A week or so ago, I discovered after 7 years that my mail server (running 
Zimbra 8) was an open relay.  :-}



I tightened it up after about 4 hours, and checked a couple RBL checkers, 
(MXtoolbox and anti-abuse) and there were only 3 hits for the IP, and I 
requested clearance on them, and got it, and both now show all green...



but when I tried to send someone at hotmail an email today, I got the below 
bounce, which includes an error code, and a link to a page of error codes 
*which does not include that code or anything like it*.



Is there someone on here from outlook.com or the protection subdomain, who can



  a) tell me how I *would* clean that up -- the linked page of error codes

 mentions Spamhaus, but they seem ok with me too, and



  b) clean up either the SMTP error message you're sending out or the table

 you tell people to look it up in?  :-)



Cheers,

The Exchange Protocol, as I understand it, allows nFA, while IMAP does not.

Or that is what I have been told.

I read a bit more about this and "modern authentication" means also that the 
IMAP protocol to connect the the mailboxes is disabled.



Does anyone know if there is any alternative to Outlook to access Exchange 
Online mailboxes that require modern authentication?



The IT department of the organization that is pushing thins says that modern 
authentication and disabling IMAP (over SSL) enhance security. I don't see how 
this is the case. Does anyone have an opinion?



Thank you.



Cheers,

Dan

Re: [mailop] Problem delivering to protection.outlook.com

Jay, the next step here would be for you to fill out a remediation
(unblock) request with Microsoft OLC (Hotmail).

The form to do that can be found here;
https://go.microsoft.com/fwlink/?LinkID=614866

Sometimes it takes them a few days to respond.
First response will be automatic and just basically say it's in queue.
Second response might be useful or it might be like somebody just spun
a wheel of responses and it landed on a random one that makes no
sense. If so, respond and state your case. Repeat as necessary.

Good luck.

Cheers,
Al Iverson
