NC036: Emails to Hotmail/Outlook being redirected

22 May 2020 07:03:49 +0000

Some clients may have had emails they sent to Hotmail, Outlook and other Microsoft email service domains bounced in the last 24 hours. This is because the primary mail server’s IP address has been blacklisted by Microsoft, despite our being enrolled in their “Junk Mail Reporting Program”. Our being enrolled is supposed to result in our being informed of spam complaints (which are overwhelmingly false) before our IP address is blacklisted, but their system seems to have been broken for the last few years.

Until we can get in touch with Microsoft support to have our IP address removed, or until our listing expires, we are automatically directing all email to their domains through our relay server, which is not blacklisted.

If you had an email bounced, please resend it. Thank-you, and sorry for the hassle. If you have any questions please contact NinerNet support.

NC036: Mail server blocked by Microsoft

14 December 2018 05:33:38 +0000

We are aware that the IP address of server NC036 (the primary mail server) has again been blocked by Microsoft’s various mail services, variously known as Outlook.com, MSN, Hotmail, Live.com, etc.

Although we are a member of their Smart Network Data Services programme and Junk Mail Reporting Program, which are supposed to allow us to proactively prevent these kinds of issues, we have been unable to use the service as advertised, or at least as we understand it’s supposed to work. We will continue to attempt to have this server’s IP address removed from their blacklist, and report here when we have success.

In the meantime, outgoing mail to their primary domains (hotmail.ca, hotmail.com, hotmail.co.uk, live.com, msn.com and outlook.com) is being routed through our relay server. If you receive a bounce message that reads similarly the one below to an email you’ve sent, it is probably for a private domain hosted by Microsoft of which we are not aware. Please contact us and we will add it to the list of domains for which email is routed through our relay server:

host 901e3cd0af6f44ab11b5a5e8a49da3.pamx1.hotmail.com[104.47.0.33] said: 550
5.7.1 Unfortunately, messages from [178.62.195.26] weren’t sent. Please
contact your Internet service provider since part of their network is on
our block list (S3140). You can also refer your provider to
http://mail.live.com/mail/troubleshooting.aspx#errors.
[HE1EUR01FT033.eop-EUR01.prod.protection.outlook.com] (in reply to MAIL
FROM command)

Please remember that all email you send through our mail server must be to recipients with whom you already have a business or personal relationship, and all mass email must be explicitly requested — i.e., Confirmed opt-in (COI) or Double opt-in (DOI) email.

Thanks for your cooperation, and our apologies for this inconvenience.

NC036: Migration update 24 — Outlook weirdness

11 June 2018 11:35:44 +0000

Microsoft are famous for ignoring standards and inventing their own so-called standards, and over the years we’ve seen evidence of that in Outlook.

Numerous clients today report that the following applies to Outlook, at least Outlook 2016:

There is no option for STARTTLS for incoming (POP/IMAP) settings. As such, you need to use the older and deprecated option of using port 995 (POP) and 993 (IMAP) over SSL.
