With cyberattacks becoming so severe and sophisticated, your organization cannot afford to leave its email ecosystem inadequately protected. Moreover, since email is one of the most common targets for these attackers, it becomes all the more important to properly protect your entire environment. One of the most effective ways to protect your outgoing emails is…
The best practices for managing SPF records across multiple Office 365 domains are to use a per-domain baseline of v=spf1 include:spf.protection.outlook.com -all, centralize vendor authorizations via a delegated or “hub” SPF record to control the 10-lookup budget, rely on DKIM and DMARC (plus SRS where possible) to mitigate forwarding, and continuously monitor/validate changes—with automation from…
The most common issues highlighted in an SPF record breakdown are syntax and qualifier mistakes (missing v=spf1, multiple records, malformed mechanisms), exceeding the 10-DNS-lookup limit via nested includes/redirects/mx/a, misordered and redundant mechanisms that inflate lookups, gaps and overlaps when authorizing multiple third‑party senders, misuse of ~all/-all/?all, forwarding and mailing‑list scenarios that break SPF, subdomain and…
The best practices for creating an SPF record for domains managed through GoDaddy are to publish a single TXT “v=spf1” record at the exact sending domain that authorizes only your legitimate senders (ip4/ip6/a/mx/include), avoids the deprecated SPF record type, stays under the 10-DNS-lookup limit, ends with an appropriate -all or ~all qualifier, uses change-friendly TTLs,…
To verify that Google recognizes your domain’s SPF record, first query your SPF TXT record via public resolvers (for example, dig +short TXT yourdomain.com @8.8.8.8), then send a test email to a Gmail inbox and confirm spf=pass in the Authentication-Results header (or use Google’s Admin Toolbox CheckMX/Messageheader), ensuring you publish a single valid v=spf1 TXT…
Email authentication is a cornerstone of modern email security and deliverability. Without properly configured authentication protocols such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), organizations expose themselves to spoofing, phishing, spam filtering issues, and poor sender reputation. When you use Rackspace Email as a sending platform, ensuring both SPF and DKIM are…
You might create the most engaging email, but it still fails to land in the recipient’s inbox. If this keeps happening frequently, the problem may not be with your email campaigns but with how receiving servers perceive your emails. If the recipient’s servers cannot trust an incoming email, they either send it to the spam…
Yes—but with limits: Google Domains can automatically add an SPF record when you use its guided setup for Google Workspace, but it does not auto-detect or fully configure SPF for most third‑party email providers; in those cases you must create and maintain a single TXT SPF record yourself (a task AutoSPF can automate and keep…
The best practices for configuring SPF with Office 365 are to publish a single, centralized SPF policy that includes include:spf.protection.outlook.com, explicitly list any on‑prem or gateway IPs with ip4/ip6, keep total DNS lookups under 10 by consolidating third‑party senders and using flattening or redirects when needed, start with ~all during testing and move to -all…
In today’s email‑centric world, ensuring that your support and outbound emails are trusted by inbox providers like Gmail, Outlook, Yahoo, and others is critical — not just desirable. Without proper email authentication, your messages can easily land in spam folders or be blocked outright. This is especially true for customer support platforms such as Zendesk,…
