Do you need help & advice with Cybersecurity or Online Presence?
It’s a common headache: you’ve just got a new system up and running, feeling pretty good about it, only to discover that emails aren’t sending out properly. The culprit is often something called DMARC, DKIM, or SPF. These are security measures designed to stop people from pretending to be you via email and sending out messages from your domain. While they’re great for protecting your business from things like invoice fraud, they can also cause problems if not set up correctly.
Key Takeaways
- New email-sending software needs proper DMARC, DKIM, and SPF configuration.
- Incorrect setup can lead to legitimate emails being silently rejected.
- IT teams need to monitor these settings, as misconfiguration is an extra task.
- Proper setup is vital for business safety and preventing fraud.
Understanding DMARC, DKIM, and SPF
Basically, DMARC is a system that stops people from impersonating you through email. It also prevents others from sending emails using your company’s domain name. It’s not a perfect shield, but it really cuts down the risk of people pretending to be you, which helps stop things like invoice fraud and other nasty surprises. The catch, though, is that it requires a bit of setup.
The Cost of Security: Configuration Challenges
When you bring in a new system that needs to send emails, it has to be configured correctly with these security measures. If it’s not, any emails sent from that new system might just get deleted. And that’s probably not what you wanted when you invested in new software. It’s a classic case of security versus practicality.
Email, way back when, had no security at all. We’ve been adding layers ever since. When your IT team enables things like DKIM, it’s important that it’s monitored. If new systems are set up to send emails and they aren’t configured right, those emails will just get thrown away. If you don’t know this is happening and you complain to your IT team, well, that’s not going to end well for anyone.
What Management Needs to Know
So, the main point here is to get DKIM set up and configured properly. It does throw away emails that aren’t genuinely from your business, but that requires monitoring. This is an extra job for the IT team. Management teams just need to be aware: if you’re buying a system that sends out emails, you’re going to have to configure it for DMARC. The DKIM and SPF stuff needs to be set up correctly, and yes, that’s extra work. But it’s definitely worth doing because it keeps your business safer.
