DMARC Reports Confirm My Mail Server Works Properly

One of the best indicators of a properly configured mail server is consistent positive DMARC feedback from other providers — and that’s exactly what I’m seeing from Gmail, Outlook, Yahoo, and others.

I’ve configured my mail system with best practices:

  • SPF — to validate sending IPs;

  • DKIM — to sign emails with a cryptographic signature;

  • DMARC — to enforce policy and unify SPF + DKIM checks.

My domain also includes reverse DNS records, working postmaster and abuse addresses, and automated DMARC report aggregation for ongoing monitoring.

The result: my emails are reliably delivered, rarely flagged as spam, and seen as trustworthy. This is especially important for customer communication, booking forms, and service confirmations.

✅ If your DMARC reports show SPF and DKIM as “pass”, you’re in great shape.
📬 If not — everything can be configured from scratch, and I’d be happy to help.

While I’m currently seeking a new opportunity in IT, I stay active and productive — for myself and for future clients. I’m not just waiting: I’m sharpening my skills, automating routine tasks, and most importantly, working on my personal project: itbumper.com.

The site is already live and functioning. Through it, you can:

  • explore the services I provide;

  • book appointments for computer repair, Wi-Fi setup, video surveillance, IT audits, and more;

  • review service policies and document templates;

  • contact me directly without calling — I usually respond quickly to messages.

This project is more than just a website. It’s how I stay sharp, move forward, and offer real value — even during times of transition.

If you’re curious how I’ve implemented certain features on the site or have suggestions for improvements — feel free to reach out. I’m always open to feedback and ideas!

Today, I saw the vacancy, and I knew I had to take action. Sure, I’ll start small — but when has that ever stopped me? Life once tore out my roots, and I had to leave much behind. But I kept the seeds. New roots will grow stronger. And I’ll make it happen!

Many years ago, I deployed the company`s Help Desk System based on OTRS 5 and it was a great experience, and now I plan to move on GLPI. It`s open source as well but it has more options.
I`ve deployed a new one for the test and I like it. I think in a month I`ll make a production server.

Last week I said goodbye to a Kerio Mail server which was working on Windows system for years. I deployed a new open source email server iRedMail, of course it has some limitations, but I spent some time and figured out, how to handle with them by manipulating with a SQL database. That is a good solution for SMB and Home offices who don’t trust clouds solutions anymore.

The first post is from 2025. In January, I deployed two Wire Guard VPN servers, wrote several management and automation scripts, and distributed some of the addresses to friends who have long had problems accessing, using, and liking various services. I wanted to clean the code from confidential technical information today and publish the script code, but no luck; I got into a car accident today. At the intersection, another car flew into my car from behind. No one was injured, but we will fix the iron and plastic. I liked the man’s behaviour. He avoided unnecessary words and emotions, keeping our composure. We exchanged contacts, and everything went well without unnecessary fuss. However, I had to get out my laptop to download the insurance. I should print it out and put it in the car.

That‘s how I went to a meeting today, and there’s a lot of work in the evening; something needs to be done with insurance; I have zero experience in this.
