My brand-new domain is giving me two headaches at once: the site refuses to load as some antiviruses are blocking it, and email sent from the same domain rarely reach an inbox as thye get blocked by anti-viruses. Both problems appeared right after we moved our new website to this domain, so I suspect a misstep in DNS, SSL, or mail-authentication records—but I haven’t been able to track it down. I need a clear, methodical check-up that isolates the root cause, restores normal site access, and gets email flowing to the inbox again. Once everything is stable, a brief hand-off note outlining the fixes will close the loop.
