[BlueOnyx:20685] Re: Mail to Microsoft Customers

[Fungal Style]

Personally I have no issues, it does appear that you may be on some form of black list or sending too many emails too quickly to Yahoo Inc, ot Microsoft Inc domains… they are different companies.

Microsoft’s suggestion of :

Mail rejected by Outlook.com for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation. If you are not an email/network admin please contact your Email/Internet Service Provider for help.


Would be a good start, maybe try searching for your IPs in a black list site, or just try a google search for something like:
abuse <ipaddress>

Where you would enter your IP address of the mail server… you may need to do what I had to with AOL and do all the reverse lookup SPX, etc (insert favourite jump through hoop step here).

HTH

We have had problems in the past sending e-mails to Microsoft companies (yahoo, outlook, Hotmail etc) from our BO box.

The message we get back in the log is

Feb 20 13:54:01 centos7 postfix/smtp[549]: 0D4B13F28A49: to=<xxxx87 at hotmail.com>, relay=mx2.hotmail.com[65.54.188.126]:25, delay=24, delays=23/0/0.14/0.04, dsn=5.0.0, status=bounced (host mx2.hotmail.com[65.54.188.126] said: 550 SC-001 (BAY004-MC4F21) Unfortunately, messages from 208.67.xxx.xxx weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. (in reply to MAIL FROM command))

For the last few months we have been fortunate to have access to a machine that is allowed to deliver to Microsoft domains. But due to circumstances beyond our control, we are losing access to that machine next week.

I have spent a lot of time reading the nonsense document at mail.live.com and am no closer to understanding what we have to do.

How is everyone handling getting mail delivered to Microsoft customers?
