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: Migration update 23 — SMTP AUTH is required for users under this sender domain

11 June 2018 09:38:23 +0000

There are two reasons why you may be getting the above error in response to messages you’ve sent to addresses on domains hosted by NinerNet, likely your own domain:

  • It may be because you’re sending from an address on a domain that we host, but instead of sending your email through our SMTP server (smtp.niner.net) you’re sending through another SMTP server, possibly that of an ISP or another email service provider. In some cases this can happen because of a situation similar to that described in the sixth bullet point of our post “NC036: Migration update 20 — Solutions“, where you’ve sent the email through a third party, perhaps an ISP, or an email account you have with another provider.
  • If you’re using some cloud-hosted application that tries to send email to you as you (or another user on your own domain), then that email looks like spam to the mail server, because lots of spammers mistakenly try to get their email through by sending their spam from your email address to your email address, or from another address on your own domain to you.

The solutions are, respectively (and respectfully):

  • Configure your email program to use smtp.niner.net to send email from any domain that we host. If you’re following the configuration instructions we send you, then that is the case by default, and always has been.
  • Have the provider of the cloud service send those emails from an address — even a “no-reply” address — on their own domain, or use SMTP AUTH to send the email through smtp.niner.net from an address on your own domain, just as you or any other human with an address on your domain would.
