Re: Unable to block spam Email
Do you activated "spf hard fail" in antispam policy ? Do you set the anti-phishing in the highest level ? Do you move all types of spam to quarantine ? The spam can be blocked by mail account, by domain of account , by the name of host, by domain of host, or by the country, and so many options in anti spam policy. You can see all mail information in the Azure mail header analyzer. https://mha.azurewebsites.net/ You need put the email header in the analyzer. The header has the host that send the mail. The spam policy is in this link https://security.microsoft.com/antispam? If mail has a URL link, you can block the domain of url in the tenant block. https://security.microsoft.com/securitypoliciesandrules?2.3KViews0likes4CommentsRe: Security Questions and Answers
Trevor_Rusher Hello ! We need a DNS filtering on cloud. Can be done within Security Center, Azure application, or with a new website. The DNS filtering is done by public static IP of costumer. The costumer configure the DNS IP of cloud in DNS forwarding of Active Directory, or in DHCP configuration. The cloud filter DNS requests by the costumer static public IP. All DNS resolutions of network can be filtered by cloud. The cloud needs a website categories and list with malicious websites. DNS is one of the first stages of attacks. Microsoft needs a public DNS to done this. The costumer associate the IP in the cloud. Thanks!1.1KViews0likes1Comment
