- 9Why am I getting DMARC and SPF errors when emails deliver fine?Third-party email marketing services often fail basic SPF checks within DMARC reports because their sending IPs are not included in your domain's DNS records, even though inbox providers still manage to deliver the messages. This discrepancy leaves administrators guessing about real deliverability health and creates confusing tool warnings that hinder proper configuration.
- 8Why do self-hosted emails keep going to spam?Major email providers constantly flag self-hosted messages as spam, leaving owners unable to reach inboxes reliably. This forces people to abandon self-hosting entirely and rely on external services like Fastmail just to get their messages delivered.
- 7Getting weird scam letters or emails from banks I don't usePeople are receiving physical letters and emails from unfamiliar financial companies and banks claiming missed payments or unknown inquiries using outdated personal information. This causes immediate panic and forces people to spend hours trying to figure out if their information has been compromised or if it is just a phishing scam.
- 7Why are security warning emails so vague?Security notifications often fail to provide specific error details or pinpoint where an issue originates, leaving teams unable to determine if their organization is actually affected. Without actionable information, administrators are forced to manually audit logs and guess whether the warnings apply to production instances or forgotten sandboxes.
- 4Which hostname should be included in a mail server TLS certificate?Embedding changing variables like OS, hardware type, or location into hostnames causes confusion and technical debt as enterprise environments scale. This creates uncertainty when selecting a lasting name for an SMTP mail server's TLS certificate CN or SAN. Using mutable server names stops teams from establishing clean naming standards that hold up as hardware or server roles evolve.
- 3Why do Power Automate flows break when EWS is disabled?Disabling Exchange Web Services blocks legacy protocols used by standard email connectors like Office 365 Outlook. This causes automated workflows such as Power Automate email actions to fail across your tenant unexpectedly.
- 3Why does Outlook keep showing Access Denied or throwing errors?Outlook desktop occasionally stops receiving new mail and displays an "Access Denied" badge or error messages, while Outlook on the Web throws network errors. These intermittent sign-in loops and authentication failures require users to repeatedly clear Credential Manager or wait for access to restore.
- 2How to secure vendor emails on personal devices without MDMOrganizations often need to give external contractors and vendors access to company alerts and browser-based apps on their own personal computers or phones. Because these workers are scattered globally and use bring-your-own-device setups, companies want to avoid invasive MDM enrollment or complicated user exceptions while still protecting corporate data.
