Ensuring email from an IP isn't blocked by Hotmail / Outlook

An important first step to make sure email sent from your IP isn't blocked is to review its status on known 'blacklists'. Instructions on this are available in our  article: Determining if a server is blacklisted: https://kb.iweb.com/hc/en-us/articles/230267148-Determining-if-a-server-is-blacklisted.

You should also verify your server's mail queue content or outbox (current size and outbound email traffic statistics) to identify unusual activity levels.

Follow these instructions to unblock your IP from Hotmail / Outlook:

1. Ensure Compliance: https://mail.live.com/mail/policies.aspx

2. Follow best practices and FAQs: http://postmaster.live.com/Troubleshooting.aspx

3. Configure your reverse DNS on your IP addresses: https://kb.iweb.com/hc/en-us/articles/230242968-Configuring-Reverse-DNS-Control-Center-or-Customer-Hub-

5. Configure your Sender Policy Framework information on your IP addresses: https://kb.iweb.com/hc/en-us/articles/230245188-Adding-SPF-records-to-domains
